My OLPC stucked off after starting up and please also guide me that from where i can get
new charger for my olpc?


== Question ==
We are planning to help OPLC but we need to check the Financial Statements of the organization. Does somebody know where can we get this information?


:From OLPC directly, or the government or other regulators. I don't think you should rely on what contributors to a community Wiki might tell you ... that's not a rigorous method. --[[User:Quozl|Quozl]] 03:23, 13 February 2012 (UTC)


== Question ==
I turned on my OLPC but it didn't show anything.What do I do?


:Check out [[Keyboard freeze fix for os 650-656]] it might be your problem. Hard to say, unless you can give some more information, like when you last used the XO, whether the power indicator turns on, whether the display backlight turns on. --[[User:Quozl|Quozl]] 21:04, 30 August 2011 (UTC)
== Question ==


how do download windows xp on to my olpc xo and how do you access your downloads


: There is no way to get Windows XP for your individual OLPC. Microsoft does not make it available to individuals, and OLPC has nothing to do with that.
==Usability and User Testing==


== Downloads ==
There is very little public information about requirements gathering, usability and user testing. In other words, how do you know whether the OLPC (i) will meet your users' needs and (ii) is easy enough for them to use? Have the target user groups been characterized? What ongoing plans do you have for this?
How to access your downloads?
I`d Like test the OLPC in Argentina, Please contct with me to know how.
: If you download things on the OLPC, they should show up in the Journal, which is one of the Activities that's always running. It looks like a little spiral notebook. You can also open the journal by pressing the "magnifying glass" icon in the upper-left hand part of the keyboard.
Thanks.
:As far as I know, there are two local groups in [[OLPC Argentina|Argentina]] with test boards (don't know if anybody has the 2B1/XO prototypes though). They are [https://www.ututo.org/www/modules/downloads/downloads.php?ID_downloads_category=21 Ututo] and [http://tuquito.org.ar/olpc/index.php?title=Portada Tuquito]. I know [http://www.ututo.org/ Ututo] had some explicit arrangements to let other people use/test the boards. If anybody knows about other groups (or about any local XOs) please let me know (or post in the [[OLPC Argentina]] pages. --[[User:Xavi|Xavi]] 07:23, 6 December 2006 (EST)
:There is more to life and education than requirements gathering. Usability and testing are of course important, and on-going. Research is often just trial, error, and adjustment. If you want, you can participate by setting up an emulator and seeing how the software works now. The research is going on now, and you can participate. Exciting, don't you think? -[[User:Jcfrench|Jeff]] 21:47, 9 March 2007 (EST)


== how do you start your downloads ==
What about usability testing for children? A recent article quoted the OLPC chairman as saying: "Granted, I'm not a child. I don't know if it's going to be intuitive to children." Was there research?


I downloaded adobe flash player but i still can't watch my videos i know you go to journal and the file and click start but it doesn't work.

== How do I chat with other people in the world? ==


My xo is hooked up to the internet but I still don't know how to chat with other people in the world could you tell me how please?
==Accessibility==
: First connect to a [[Jabber server]] or your local school network. Then you can see other people on your network and will be able to chat with them.
: You can also download [[XoIRC]] and chat with people using that activity. 02:34, 17 December 2009 (UTC)
== Downloads ==


How do I download music on my labtop?
What mechanism olpc is going to adopt to make it accessable for child with physical disabilities? Will there be seperate keyboards for blind with braile? Will there be alternate input methods for child with dysfunctioning hands?
: Click on a file to download. Then open it from your [[Journal]]. Alternately, install an activity like [[Jukebox]].


How do I download Doom?

== Reset settings ==
:As far as I know, OLPC keybords are standardized for each country's language/s, but not braille. The OLPC has [[Hardware specification#Specifications|3 USB ports]] to which external (braille) keyboards may be connected ([http://www.google.com/search?client=opera&rls=en&q=usb+braille+keyboard&sourceid=opera&ie=utf-8&oe=utf-8 quick search] and [http://www.portset.co.uk/braillekey1.htm sample result] or [http://www.hooleon.com/menu-stickers-braille.htm?gclid=CNWevcfho4kCFSiANAodGG3twA alternative method]). In order to better gauge the dimension of the issue, the [http://www.who.int/ World Health Organization] (WHO) has some statistics on the [http://www.who.int/mediacentre/factsheets/fs282/en/ incidence of blindness].

I need to knnow how to reset the name on my xo laptop
Further to the question above, does the OLPC initiative include distributing laptops to children who are currently going through patient care in a hospital setting? And if so do you have links to devices that can allow a child to utilize a laptop from a hospital bed (i.e., wall mounted mechanical laptop ARM)? This is a great initiative!!!
: From the [[Sugar Control Panel]], update your "About me" settings, and restart. 02:34, 17 December 2009 (UTC)


== Viruses ==

How Do I erase viruses from my xo
:Technically, it's the governments '''buying''' the laptop that will distribute them ('''not''' the OLPC), and while I see no difference between a child in a hospital bed or a cabin in the mountains (from a distribution PoV), my guess is that hospitals in these countries have other priorities to allocate their budgets instead of [http://www.infologixsys.com/products/Healthcare/Healthcare-Solutions/Point-of-Care/Wall-Mount-Workstation/C-Wallmount-Cabinet/default.asp fancy trays] (as cool as they might be ;) --[[User:Xavi|Xavi]] 08:05, 23 January 2007 (EST)

== reset journal info ==


my question is how do u erase information on the journal
As a representative of an NGO type organization I just recently commented to a UN officer about a similar subject. “Fancy Trays”' are not always at the request of the country or donor agency in general. Part of what makes these items or services that may not at first glance seem functional is the vision of the donor. Just like the water go round in Africa sponsored by Ex US president Bill Clinton and the water see saw in another nation that promotes the washing of your hands. It is not always up to the receiver in what it is they are to receive .
There are also many sites that go in-depth about theses issues and the how and why's of the matters. If you are interested in finding out more you can direct searches about: third world programs, world aid and I am sure you can find more information as to why a fancy tray may have been purchased or donated as well as many other interesting things.


hey guys nice work ...well i am making a project on u guys can u help me with the list of countries whu r a part of ur process
== I question whether there is some benefit for us or you by getting involved ==
thanks

Peace out


== Two activities ==
We are a St. Louis MO based charity doing Health Related activity in many poor parts of the world including Ecuador, Africa, Asia etc. We have recently been asked by Ecuador officials to assist in several different activates, including build schools, clinics, furnish computers etc.(we have a current request for 100 computers that we are trying to fulfill.


hey i've got 2 questions
Or name is Wings of Hope and you can view our website at www.wings-of-hope.org to get some idea of what we do and who we do it for, both locally and around the world. We are a volunteer organization with pilots, nurses and support people stationed in many countries in poverty stricken areas. We are non political, non religious based, have no ethnic motivations nor any other motivation based issues except to help people in need.
1. first of all why won't my eye chat open even if i have downloaded it
2. second how can i read e-books on my olpc
oh and one more question: can i contact the child who got the other laptop after i had paid for mine?
thanks
:Thanks for your questions. Sorry, I don't know what eye chat is. E-books in various formats can be read using the Read activity, and there are new E-book reader programs on http://activities.sugarlabs.org/ . No, you can't contact the child who got the other laptop. -- [[User:Quozl|Quozl]] 22:46, 26 July 2010 (UTC)


== How does the Log Viewer work? ==
We furnish air transport service to poor people in the central part of the United States to get them to health care facilities. We set up health clinics in poor areas of the US and we Donate aircraft to many areas of the world to be used as Air Ambulances. The website above will reveal a lot about Wings of Hope activates.


Dear Sir/Madam,
I saw the article in Popular Science about your computers and I just feel there is something that we can offer that will advance your cause. Our relationships appear to be with the kind of folks you are trying to reach. If you feel we can be of any assistance to your efforts, we would like to discuss the issue(s).


As a part of an evaluation project we are trying to determine what activities are being used by the children, and for this reason we would like to know exactly how does the log viewer work. The journal presents the problem that activities may be erased by the children, therefore not providing a complete picture. So my questions are, what does the log viewer exactly show? Does it show all the activities used by the children? Does it only show errors in activities used by the children and if so what type of errors? Do you think the log-files can be used to determine what activities are the children using or the information won't be reliable towards that purpose?
Please Contact our Director, MR. Douglas Clements, www.woh206@earthlink.net or,.


Also, is it possible to recover erased activities from the journal?

== Contribution towards Programming ==


== how to repair olpc ==
Hello,


hi olpc i am call placide and my olpc can not switch on now but the screen can switch on but does not mark any thing
I am really interested in contributing towards the programming efforts in linux kernel and python. Please let me know how shall I proceed and start contributing towards it?
so it looks like has virus or it has corrupted so i would like to know how can i repair it and what can use to repair it
please i need help


:This can happen if you hold down the rotate button when you turn it on. Please try this: remove the battery, disconnect the cable, wait 10 seconds, put the battery back in, press the power button. The laptop should start. If it does not, then it may need repair. -- [[User:Quozl|Quozl]] 04:14, 25 October 2010 (UTC)

How does a computer science professional contact OPLC about volunteering their time to help deploy the laptops and train new users? Is there an affliation with GeekCorps?

:See the section about [[Ask OLPC a Question about Distribution#Training & Capacity Building]]... but in general, that is upto the deploying countries to decide how it'll work - you should contact that side of the equation (or any organizations they name when the time comes).--[[User:Xavi|Xavi]] 17:54, 13 January 2007 (EST)

== Where can I see an OLPC in the UK? ==


Hi,
Hi,
I am am a new learner in this OLPC deployment team. I have installed a OLPC XS and had a problem with the eth0. During boot process it come to a stage where it says that IP determing information on eth0 fails. I have follwed the proper steps to install the server however it still gives me the same problem.
Can anyone out there assist me to get the eth0 working on my server.

== Skype microphone issue ==
I'm really interested in the OLPC project, and often add things to the wiki... But I've never actually seen one in real life... How many are there in the UK, and what are the chances of actually viewing one? Maybe you should do a grand tour?!


I have been using Skype on my XO1 with ver. 656 without problems but after updating to ver. 802 and re-installing Skype using the directions given on http://wiki.laptop.org/go/Skype (Standard) the sound of the microphone is garbled, when placing a test call, even though it is clear when recording in terminal mode by using arecord and aplay. I have tried several settings in Alsamixer and Skype but without getting any change or improvement. Is there a patch or fix for this problem. Updating to ver. 852 did not work as Skype will not install on the 852 version on my XO1.
:Well, you can try the alpha software in emulation: [[Using QEMU on Windows XP]]. If you run into problems, you'll have to research and learn. --[[User:Jcfrench|Jeff]] 27 Feb 2007
Note: I re-installed 802 and Skype several times and in several different executions following posts under OLPC but always with the same result. Placing a test call in Skype gives a playback with garbled microphone sounds like two voices overlapping each other and then shorting out.

I do not see any content related sections for the sciences (physics, chemistry, biology) and math. Can you please point me to that section or include this in your curriculum?


Hello
:Every page has a search section in the column on the left. If you don't see something in the table of contents then use the search capabilities to find it. If you still can't find something which you think should be on the wiki, then start a new page and write an outline of what you think we should have. Others will fill in that outline for you.

I am having trouble updating from the 656 system and now my mouse and keyboard has frozen. Can you please advise me. Thank you. -- heather


:Hello Heather. What have you upgraded to? Does the mouse and keyboard remain frozen if you remove the power adapter and battery and put them back in? Write to {{help@laptop.org}} if you'd prefer e-mail. --[[User:Quozl|Quozl]] 02:01, 3 January 2011 (UTC)


::Hello
::I tried using the email but only got a generic response. To answer your questions:
::- I was trying to upgrade to the 10.1.2. I tried with the USB method and got the grey grid with a message underneath, something about NAND and size.
::- I then tried to update in terminal using all the various wordings proposed. That did not work either. I left the machine for a day or so and when I turned it back on the mouse and keyboard were frozen. When it lit up with the clock, it would go to a black screen with some text at about a quarter of the way round and then, before I could read it, it would go back to loading. I tried turning the machine on holding the O key which made the black text screen disappear but did not fix the freeze. I tried removing all power. I tried turning the machine on holding the rotate button. Nothing has worked yet. I'm really excited that you are responding to me and look forward to finding a solution.
::Take care. -- heather


:::Did the generic mail response give you a tracking number? If so, let me know what it was. That will help us mark it as being handled.


:::The grey grid sounds good, the message does not. There may be a fault in the laptop, or a problem with the download or preparation of the USB drive.


:::The grey grid occurs with an install of 10.1.2, so I'm presuming you are wanting to do an install, which wipes all data off the laptop. If so, please try again and this time check that you are following the install instructions below and tell me exactly what the message about the NAND says.
== Adaptation of Musical Editor for local music systems ==


:::Regarding the update in terminal, I don't think you should try that again, because having started the install the contents of the internal storage is undefined, and the results may be unpredictable. The mouse and keyboard freeze is common; it happens if the laptop runs out of memory. We didn't test update from 656 and it may not work.
Hello,
While browsing through the software that will be put on the B2 release, I remarked the screenshot of the Musical Editor, and I saw that it was based on the western notes system (do, re, mi, fa, sol, la, si, do). These notes have more or less fixed frequencies ('la' has 440 Hz, and going from one note to another happens by stepping of halve tones where the frequencies need to be multiplicated or divided by 1.059, the twelfth root of 2).


:::Feel free to send me an e-mail at quozl@laptop.org if you like. --[[User:Quozl|Quozl]] 22:24, 4 January 2011 (UTC)
The OLPC project is ment for children in third world countries, like for instance India and China and other countries, where different music systems are used. Therefore I propose to foresee these adaptations within the Musical Editor (after all, it can't be the intention of forcing children to abandon their own musical culture :-?).


{{Software_Install|path=http://download.laptop.org/xo-1/os/official/os852|release=10.1.2|build=os852|model=XO-1|signed=yes}}
In case OLPC people are interested, I am willing to do some investigation in order to figure out which are the mostly used music systems with corresponding frequencies in order to facilitate the work. I can be reached via my e-mail address under my OLPC subscription account 'scampsd'.


== Activities disappear ==
:The OLPC includes [[csound]] software which can be adapted to work with any type of musical system. If you want to document these systems and any csound software that works with them, feel free to start a new page on this wiki. --[[User:Memracom|Memracom]] 05:30, 13 January 2007 (EST)


What to do if all of my activities disappear? Please Help!!!
Best regards and good luck with the project
:Reinstall might be a last resort. Someone else asked this recently, and it turned out that changing the language to one that isn't supported may cause this. Change it back. --[[User:Quozl|Quozl]] 23:38, 1 February 2011 (UTC)

== Wi-Fi WAPs not visible in Neighborhood View ==


I installed the 10.1.3 version to my XO-1. Initially everything was fine including the WAP icons. Now I am only seeing the MESH target icons. I know the access points are working in several locations including m home one but still nothing but MESH is visible in the Neighbothood View. How can I fix this, short of trying a reinstall of 10.1.3?
---from another contributor---
:This will happen if automatic power management is enabled, which is the default, and the laptop is not kept awake for at least a minute. This is in the [http://wiki.laptop.org/go/Release_notes/10.1.3#XO-1_Automatic_power_management_issues release notes]. Try turning off automatic power management in the control panel. If that does not change things, please use Open Firmware to check the wireless card. Obtain the [[Ok]] prompt, and type ''scan-wifi'' then press return. This scans for wireless access points by turning on the radio receiver in the wireless card. Doing this test in Open Firmware is useful, because it excludes the 10.1.3 software entirely. If it doesn't show any access points, then there's no chance that 10.1.3 will. If it does show them, but 10.1.3 does not, then at least we know the problem is not hardware. Let us know how you go, because based on this test there are very different further tests to make. --[[User:Quozl|Quozl]] 23:20, 4 May 2011 (UTC)


== how to format my olcp XO 1 ==
yes - i can see nepal, peru, thailand and india on the pilot project map that will be using different scalings 'naturally' without the fixing of the western scale to their use of the software.
please please i can ask you how to format the olcp and how to remove the downloaded applicattion which can not be erased please if u know it tell me quickly or send it on my email : saemscolomb@yahoo.fr
from the wikipedia.org page on microtonal music:
: One way to clear all changes would be to re-install or update to a current version. See [[Release_notes/11.3.0#XO-1]] or [[Release_notes/11.3.1#XO-1]] (almost released). --[[User:FGrose|FGrose]] 17:27, 10 June 2012 (UTC)
"By this definition, the following systems are not microtonal: a diatonic scale in any meantone tuning; much Indonesian gamelan music; and Thai, Burmese, and African music which use 7 approximately equally spaced tones in each (approximate) octave."
- there should be a module in csound for microtonal music: the most sensible option would be to have a special settings page to configure a preset choice of tunings for different regions to fit with preferred choice of tuning for the region. to eliminate locally tuned music would be an ethical crime, and is a big risk with a music program dictating that users have a 'western scale' for their music. i would not like OLPC to be responsible for the destruction of some of the most musically interesting and unique styles of music simply because there was no option for local tunings in the easily available and (relatively) powerful sequencing capabilities of freely available computers. it looks like Csound’s value converters for microtonal programming are functions "ampdb" and "cpspch". documentation on csound available at www.csounds.com/chapter1/index.html


== Random generator entropy ==
== How to repair olcp ==


Hi olcp i want to repair my olcp the problem is that when i charge my olcp the orange color which shows you that the power is going in but it shows like it is charged but it is activated the xo is loading when the circles are surrounded xo the laptop turns off so how can you help me to fix it.
Hi, we came up with this issue at the 23c3 in a lecture about the /dev/(u)random generator in Linux. The algortihm gets most of its entropy from the harddisk. Because the OLPC lacks a hdd, this could be an issue, when you need a random number for cryptography at boot time. Of course the algorithm is still strong and sufficient enough for most applications (or at least i think so), but not as good as some people maybe think. (Other entropies: camera, microphone,...) (DustyDingo)


== my olcp can not start up ==
:Your question is confusing, as I'm not versed in random number generators based on hard disk... Isn't the built in Flashdrive good enough? It acts like a conventional hard drive, but it's all memory. --[[User:Jcfrench|Jeff]]


Hi my name is Robert my olcp doesn' t start up when i turn it on but it turns itself off plesase help me if possible.
::No, the flash is not good at all. Hard drives have unpredictable timing, and thus the kernel uses them to supply /dev/random data. The DCON chip really should be modified to include a random number generator that works based on electrical noise such as the thermal stuff in a semiconductor junction. (note: NOT a pseudorandom number generator) [[User:24.110.145.57|24.110.145.57]] 19:40, 27 February 2007 (EST)

:::Hmm... Chaos Communication Congress... OK! So you are looking for a way to seed a random number generator from an on board OLPC component (mostly for cryptography a boot time). OLPC doesn't seem to prioritize encryption as a core value (it seems to go against the BitFrost mantra of transparency). That said, you've got a pair of WiFi like transmitters, a monitor, keyboard, touchpad, battery, etc. Does hard drive access time really provide an evenly distributed random number? I find that hard to believe. Also, is this topic really critical to the goals of OLPC as a project? --[[User:Jcfrench|Jeff]]
me gustaría saber s puedo hacer algo para sacarlo!

== Super trouble with OLPC ==
::::The very first thing an OLPC XO does is generate a long-term public/private key pair. All the over-the-air stuff is at least cryptographically signed. If a kid publishes a Sugar XO bundle, it gets signed with his key. Hard drives are decent; the fast-moving air inside the drive provides randomness. The WiFi may be a tolerable choice; it's both public and subject to lack of input though. The monitor is no good. The keyboard and touchpad are OK, though very slow. The battery is unlikely to help. The digital camera may be the best choice. The microphone is tolerable. Use of many of these devices will require lots of power and/or background daemons. It's just way easier to do as Intel did with their motherboard chipsets. VIA put a random number generator right in the CPU. [[User:AlbertCahalan|AlbertCahalan]] 22:14, 28 February 2007 (EST)


hello friends! (first pardon me with the bad English...)
:::::This is a serious issue. There's a paper on the quality of the linux kernel RNG, and how it has relied on obscurity. When people wanted to find out how it works, they got no help from the developers; after analyzing it, they found serious weaknesses, and published.


well, actually I'm repairing an XO-1 laptop OLPC, at the beginning it worked flawlessly, until i upgraded the bios firmware downloaded from: http://wiki.laptop.org/go/OLPC_Firmware_q2e45, after the process, it won't boot anymore. the trouble is i can't figure out how to make it boot... i installed this build: http://wiki.laptop.org/go/Release_notes/11.2.0 no luck... always end in the OK command prompt... same thing happened to every build version I've tried, downloaded and installed from here: http://wiki.laptop.org/go/Release_notes also, I've tried to re flash the bios and no luck, i use several ROM files, from the Q2E41(the original ROM bios that comes in my OLPC) to the last Q2E45, and still no luck... I've tried to install SO images with several SD cards with 1, 2, and 4 GB of storage capability, all of them formatted in several ways: FAT, exFAT, vFAT, FAT12, FAT16, and FAT32... and nope...the OLPC won't boot... then I've tried luck with 2 kingston USB memory sticks, one is a 1GB and the other is a 8GB storage capability, tried with FAT, exFAT, vFAT, FAT12, FAT16, and FAT32 formats, it install the OS image in the OLPC, but still the laptop won't boot... Tired of this, i get a developer key from here: http://wiki.laptop.org/go/Activation_and_developer_keys, and tried it without any luck at all...

::::::It is a serious issue, but that stuff about Yarrow being better is wrong. People get recognition by publishing alarmist "research" about supposed defects in important software. The Linux developers have little time to help clueless people who won't study the history behind the Linux /dev/random and /dev/urandom devices. Yarrow has one feature of dubious value: it recovers quickly from an attacker who somehow exposes the content of the pool. If an attacker can do that, you have bigger issues to worry about because the attacker is reading your kernel memory! Yarrow does have two weaknesses. First, it assumes that there will not be a successful attack against the cryptographic operations it uses. The Linux /dev/random and /dev/urandom instead assume that such attacks will be somewhat successful, and thus does not depend greatly on the cryptographic operations being unbreakable forever. Second, Yarrow fails to track entropy. Even if no data goes into the pool, you can pull infinite data out. This makes Yarrow a pseudo-random number generator. Linux makes a conservative estimate of the amount of true randomness available in the pool and will cause /dev/random to block (stall) if there is not enough available.

NOTE # 4: the battery is fully charged, and the AC adapter is in outstanding performance.
The AMD Geode LX processor includes a hardware random number generator. Linux's /dev/{u,}random uses it to seed the entropy pool. Also, keyboard and trackpad input are used to add to the entropy. There should be few issues with the quality of the random numbers.


NOTE # 5: all the internal memory chips are in good shape, also I've made this process: http://wiki.laptop.org/go/XO_Flash_Bad_Blocks, and the flash nand only got around 15 bad blocks... then i made this process: http://wiki.laptop.org/go/Fix_Clock and nothing, the OLPC always ends in the OK prompt, and never run the installed OS image...
::Look at the [[Measure]] activity - it reads unbiased voltage data from the audio in port. I don't know how sensitive the a/d on that is, but if it's sensitive enough to get some random noise when there's no mic attached, this would be an excellent, constant source of random data (I saw an article once arguing that a noisy a/d is either brownian motion - which has quantum input from molecular vibration modes - or direct quantum tunelling of electrons in the chip. Quantum random = gold standard.). I don't know if there are Bitfrost/Raibow issues with accessing this port - I think that's only for the physical mic, not the port. --[[User:Homunq|Homunq]] 11:06, 24 September 2007 (EDT)

== About emulating the OLPC disk Image ==


any responses here or in my e-mail dj.electron@gmail.com with help to solve this mystery, are welcome .
I am not sure where to post this as it's a rather technical support like question. I am emulating the OLPC image (I am using olpc-182.zip) in a intel iMac using VMWare tools beta. The emulations runs well, but with a limited size (640 x 480) and I know the laptop goes way beyond this. I have read somewhere an email from the OLPC mailing list that this was a recurring issue and many of the blog posts with screenshots and reviews of the SUgar interface where getting it wrong because of this.


Regards!!!
I wanted to investigate this further (and help correct those blog reviews) and posted this question to the VMWare foruns, but they believe it's a problem with the OS image.

Hello!


how do i use regular sites to download music?
I've heard about your project on the program "Click" at BBC World.
I think the idea of a 100$ computer is absolutely marvelous!


== installing firefox9.0.1 ==
I would desperatly like to get one of these computers myself, eventhough I can afford usual computers.
The problem is, that I'm living in Switzerland, which is still tinted grey on your world map.


how do i install Firefox 9.0.1?
I would be prepared to pay double the price (200$) to get one of these computers.
I don't have terminal and i cant download it.
That way, you could actually build two of them and donate one of them to a child that really needs it.


== Mouse touchppad ==
I think it would actually be a great idea to allow people who aren't eligible to own one of these computers, to get one for double its price - thus financing a free notebook for a child who really needs it.


the mouse pad on my OLPC laptop is not working,the whole thing is not working. i have tried restarting my laptop but the mouse pad is still not working, what can i do to fix this? thank you.

== I'd like to help teach. ==

I think your idea is marvelous! I heard recently about how cell phones are benefitting rural peoples in Africa, where landlines are almost non existent. and I can see how OLPC could be similarly beneficial -- perhaps more so.

Are you are recruiting folks yet to help train teachers or children to use the laptops? I've worked as a newspaper journalist, writing instructor, and am now in marketing and public relations for a community college. But I'd like to do something more meaning and helpful on a larger scale. How can I find out if there is a use for my skills in your organization? I am willing to work oversees and in primative conditions.

:The OLPC does not actually deploy the computers in these countries. If you want to work in the field, then start by reading our news section to see where the first computers are headed. Then contact the ministry of education in one of these countries to offer your services. They will likely be working together with one or more charitable organizations who operate in their country. Currently, Brazil, Libya and Rwanda are target countries. --[[User:Memracom|Memracom]] 05:40, 13 January 2007 (EST)






== School Gateways follow follow up ==

Thank you very much for the response on School Gateways -- I had a big misconception about the internet. I am still curious, however, about how the School Gateways for the mesh networks are intended to be powered, and how much energy they will require. I looked at the power page, and it mentioned microbial fuel cells, which is what I was going to ask about. Are the gateways going to require a lot more power than a microbial fuel cell could provide? Thank you!


---(JK, USA) There ought to be a sister project of the OLPC to bring internet connection to schools in the developing world. One internet connection per school wouldn't be a bad name for such project. Wireless Gateway/APs powered by environmentally friendly and renewable energy sources like solar or wind power, perhaps linked to a bidirectional satellite internet receiver, and then use [http://wifipaypal.sourceforge.net/]WifiPaypal so that donors in the developed world can donate mothly Satellite connection bill direct to the schools using Paypal.

*I think you should develop your idea and get about doing it. Gus, Chile

Yes, that would be great to get internet capabilities, I agree -- I hope you do start that up!

Does anybody know about the approximate power needs for the gateways? I know somebody working on microbial fuel cells and he asked me to find out what the power needs would be, and I just have no idea. I'm assuming that power is going to be a biggish issue for the gateways, as many of them will be in areas with no elecricity -- Am I wrong? Thank you!

::Actually, the B.A.T.M.A.N. free software for mesh networking is the most complete, widely deployed implementation of mesh networking under Linux. It's been running in production use for more than a year, which is more than anyone can say about the OLPC Marvell/CozyBit mesh. B.A.T.M.A.N. may well be useful for wide area networking of the school servers (the 802.11s mesh will only extend as far as the WiFi radios can reach; there's no plan to extend it via DSL or wired links to other parts of the network). Does B.A.T.M.A.N. support IPv6 yet? I concur that you should contact Jim Gettys at the [[Developers program]], and ask for laptop into which you could port the software. --gnu



== RealPlayer in OPLC and applications download ==

We are developing some applications that can be used to education purpose and we have some doubts:
- Is it possible to make applications download using the OLPC ?
- Is it possible to run the RealPlayer in OLPC ?
Thanks in advance
Vivian
(vivianlona@hotmail.com)

:The OLPC is based on downloadable activities, not applications. It will not have any RealPlayer support so you will need to encode in an open-source format. Ogg/Vorbis is good for music while Ogg/Speex is better for pure voice recordings. Read the [[Activity bundles]] page to see how to program a downloadable activity in Python.

:: What format do you require? RealPlayer can play many different formats. Quicktime can be played with [http://gstreamer.net/ GStreamer] through [http://www.openquicktime.org/ OpenQuicktime] and [http://www.gnu.org/software/gnash/ Gnash] is mostly SWF v7 compliant (this makes Flash an open-source format). Gnash can play Flash movies from local files. If you would like to see either GStreamer or Gnash included you could add them to [[:Category:Feedback]]. [[Thin client]] explains about use of the OLPC as a web client or thin client. --[[User:Fasten|Fasten]] 11:40, 31 January 2007 (EST)

See also: [[Flash Player]]

"Activities" is just OLPC jargon for application programs. Don't be put off by people "correcting" you on that.

Real has been working to produce an OLPC version of their Helix Player, which is a free software player. The big problem is codecs -- most of the ones in common use (e.g. MP3) are patented and require the payment of commercial royalties. If you want to produce multimedia for children and make them useful to kids with OLPCs, then you will need to take care to encode your multimedia into freely licensed formats (Ogg Vorbis for music; Ogg Speex for speech; Ogg Theora for video). These can, of course, also be played on proprietary systems like Macs and PCs, though to encourage the use of their own locked-down formats, neither Apple nor Microsoft ships these free codecs with their OS; your application will have to install them.

The Gnash flash player doesn't come with any codecs; it relies on GStreamer to decode any media embedded in the flash movie. OLPC can distribute gnash, since it's GPL software, but can't distribute the codecs needed to play "FLV" (Flash Video) files, because they are proprietary to Adobe.



== Preventing Porn/Adult Content? ==

At launch time will the laptop include any software for content controls (to prevent porn, etc). I realize that one's definition of "acceptable content" varies over regions, but isn't most content filtering software for the client Win-based?

: This will, as far as I know, be left up to countries. Because the hardware and software OLPC will provide is as open as possible, there is no real way to implement such filtering on the laptops themselves; the kids could just change the software to get around such restrictions. --[[User:18.85.46.22|18.85.46.22]] 19:16, 17 February 2007 (EST)

::Since most computers will be used with no Internet access whatsoever, this is a minor problem. In areas where there will be Internet access it will be provided by a school gateway. The filtering will either be implemented on the school gateway or at a central regional gateway.

:::Sorry, but lack of the Internet won't matter. OLPC is all about locally-produced content. This laptop has a camera. Having an Internet connection is only required for worldwide sales and distribution.

:::The laptops will have Internet access. Children will be both exploring and producing content. --[[User:Walter|Walter]] 11:40, 2 April 2007 (EDT)

'''This question has not yet been answered with sufficient care''' Please click [http://wiki.laptop.org/go/Talk:Ask_OLPC_a_Question here] for a comment (on another talk page within this wiki) about the machines being used to create pornography. The OLPC team will be making a grave error if they expect developing world governments to address this issue without guidance.

: My guess is that considering that the XOs will basically access the Internet through the mesh (connecting to the [[School server]]&mdash;acting as the gateway) a simple filter or proxy can be configured... it is (imho) a worthy preocupation, but must not be taken as ''the'' issue; most kids will not care about such things, and when they do, they'll manage to get their hands on it regardless of how adults feel about it... --[[User:Xavi|Xavi]] 00:39, 23 March 2007 (EDT)

:Are you talking about a particular already existing sort of image filter? Please elaborate. What sort of proxy? The reason that I am stressing this issue is because the reactionary element within a developing country will see this as "the" issue when it hits the press and they can keep these computers out of the hands of their children. Even if computer literate people can look past this sort of issue, large traditional populations are not likely to. Again, I'm not concerned about people looking at pornography. Every single internet cafe that I visited in 24 African countries last year had at least two young men looking at porn and nobody cared. I am concerned about the video camera being used to exploit poor young women and children. Whoever is putting this project together doesn't seem to know enough about the resourcefulness of the people who they will equip with these machines. Why isn't someone from the actual OLPC project bothering to respond. Have any of those guys actually lived in the marginal areas of the developing world? --[User:Onlinementor] 24 March 2007.

::The [[School server]] can be used for content filtering; the extent to which it will be is based upon a country-by-country decision. In regard to the children being exploited in the creation of pornographic content, it is certainly a concern, one we are trying to address through a number of mechanism, some technological, but most of a societal nature. The camera and microphone are hardwired to LEDs and are protected against remote access (See [[BitFrost]] for details). The Journal logs all activities, including picture-taking. But neither of these measures is adequate if the family and community turn their backs on their children. We are striving to engage all community members in the program, which includes guidance about the exploitation of children. --[[User:Walter|Walter]] 11:40, 2 April 2007 (EDT)

:::Thanks for the feedback, Walter. Is there somewhere on this site where I could track the conversation about how to create a suitably vigilant societal mechanism to protect against the creation of exploitative content? It's a huge challenge and while it is particularly relevant to the OLPC initiative, it is an OLD, often-confronted, unbested challenge. To paint it as a question of family and communal back-turning is somewhat misleading, as it suggests that any shortcoming on behalf of the responsible community will be committed with purposeful disregard. It is much more likely that they will be ignorant of the situation, powerless to do anything about it or coerced into accepting it.

:::I'm sure you are familiar with the fact that it is not uncommon for teachers in the developing world (especially in Sub-Saharan Africa) to use their students sexually--indeed the notion of what constitutes "exploitation" is rather variable. If you cannot have a meaningful allegiance with educators, I don't know how you hope to engender this new breed of social responsibility. I don't mean to sound glib. I would just love to hear, in reassuring detail, what sort of local and regional expertise is being applied to the question.

:::On the other page, I suggested a possibility that is less trusting of the local community; but productive of jobs and, perhaps more reliable.

A possible suggestion: Whenever someone is uploading pictures or video (via the mesh) to the internet, it must be approved by human eyes. Those eyes should belong to women in another part of the world. For instance, Uruguayan women, approve every image and video that Nigerian computer users upload. Libyan women approve every image and video that Uruguyans upload etc. It will be harder to corrupt the filter if it exists further away, speaks another language and is built of women.

The countries where you are going to pilot this program are full of women who would happily take an image filtering job for $50/month or thereabouts (and that, in many cases, would be a generous salary). Invest an extra $60,000 in each country towards the power of external, female filtering and you might be able to save yourselves considerable embarassment. In the context of this project, $60,000 sounds like a very modest investment; but it could create scores of jobs in each country and help to protect young people from the world's thirsty perversion. --[[User:Onlinementor] 2:20, 9 April 2007 (EST)


The laptop is a tool, and can be used "for good or evil". Personally I think that censorship is evil and that kids should be free to see what humans look like without their clothes. The kids I've known who grew up that way didn't turn out badly. So please stop trying to push your own cultural prejudices onto every kid in the world. If you made colored pencils for kids, would you set up a system of censorship to make sure they didn't draw anything sexy?

:::I think it's not about Onlinementor's, yours, or my prejudices. What counts is what the parents of the children want, that we are trying to influence here. They have the right to decide, if pornography/violence is accepted in their community. They should be empowered to limit the influence of the internet on their children.

:::Society change is always a violent process. The faster the change, the more violent it is. The best chance for success of OLPC in a community will be, if it does not change too much.I think it it very important to fit the filtering to the local community and their values. Internet-Access is a ''Social Change Tool''. If the social change it creates is not wanted, the programm will fail. Every community might need a different level of porn/violence/political filters, so the change doesn´t get too much. But developing the restriction mechanisms should be a high priority for OLPC. Parents/community/nation want to stay in control of the minds of their children. If you refuse to let them have some control of the new influence on their children, they might refuse the whole offer.

:::In the end OLPC has to ''listen'' to the parents of the children, and take on all their key concerns. There is no way of saying: "we from the big wide world know what´s best for your child!" -[User:Bones, 1st post] 14.09.2007

== Mesh Network Emulation ==

:Try turning on Bridge network for the virtual machines. There is an option to select that on top of the window.
By default, it is NAT.

All of the Mesh software is running inside the Marvell chip set on the OLPC, in currently-proprietary software; there is little or no support in the free Linux kernel or the Sugar UI. (Just configuration interfaces, and a way to gateway to the broader Internet.) So without the hardware, you can't run the mesh -- just an ordinary network. But since the mesh emulates an ordinary network, it's not usually a big deal. As the OLPC's higher level collaboration software starts working (soon, I hear) it should work over both ordinary networks (e.g. WiFi with an access point; WiFi in ad-hoc mode; or a USB Ethernet adapter) and over the mesh. --gnu

= Arbitrary section break 1 =

== minimum order ==

NGOs and retailers are supposedly excluded based on quantity, but that really doesn't make sense. In theory, an NGO or retailer could order many millions of laptops.

Some countries are initially excluded because they are too small. It seems you want quantities of 1 million.

Is that the magic number? If an NGO could buy a million, would you then work with them? What if Walmart wanted a million?

Would 5 million do the job? How about 10 million?

It'd be nice to replace all the "NO YOU CAN'T BUY ONE" stuff with a more-understandable "minimum order 1 million", or whatever it is.

[[User:AlbertCahalan|AlbertCahalan]] 00:42, 20 February 2007 (EST)

:The fact is that the OLPC does not want to sell large numbers of laptops. Rather, they want to get large numbers of laptops in the hands of children along with educational support for those children to ensure that they actually receive educational value from the laptops. In addition, the OLPC is at a very early stage in its project, so they need to focus their relationships on a small number of countries which are willing to put a lot of energy into pilot projects.

:There is no minimum order number because the OLPC is not selling laptops, not at retail and not at wholesale. Sometime after the pilot projects are well under way and there are a few million satisfied child users of the laptops (2 years or more) then there will be alternative distribution channels for the laptops. However, NGOs may take lower priority than small quantity projects with ministries of education in smaller countries, or poor countries which cannot support a full national rollout at one time.

:If an NGO really wants to get involved in OLPC laptop distribution, then they should start by providing people and resources to support projects in the countries where OLPC has an agreement. That way, the NGO personnel will gain experience and will be able to speak with the OLPC project on a more reasonable basis than waving dollar bills and demanding minimum-order-quantities.

== OS languages that OLPC will release ==

What are the languages that OLPC will be released with? What are the first Priority ones?

:The first priority languages are the languages of countries where the ministry of education has signed an agreement to deploy OLPC laptops to their children. In some of these countries there is more than one official language such as Nigeria with Edo, Efik, Adamawa Fulfulde, Hausa, Idoma, Igbo, Central Kanuri, and Yoruba.

:If there is a language that you would like to see higher priority then you need to convince the ministry of education in a country where it is the official language, to sign an agreement with OLPC.

== Financial support for OLPC? ==

How is OLPC supported? How does one make a financial contribution?

: You can make a financial contribution to the [http://laptopfoundation.org/participate/ OLPC foundation], which is not the same as the OLPC association. Contributions will be used for "grants and loans for the development and use of open educational resources and grassroots learning innovations that enhance the effectiveness of the XO" and for the [[Special Laptop Program]]. --[[User:Fasten|Fasten]] 17:30, 27 February 2007 (EST)

== Proxy configuration ==

Is there any way to configure a proxy in the OLPC Firefox?
:The web activity is just a version of firefox. As such, you can get to the firefox configuration by typing "about:config" in the location bar. Once there, you can narrow the settings to "network.proxy". Now, edit the fields to configure things properly from behind your corporate firewall :) -[[User:Jcfrench|Jeff]] 12:06, 12 March 2007 (EDT)







== Photo use suggestion ==

Apologies if this is the wrong place; I couldn't find a better spot on the wiki to suggest this. I hope someone can route it for me.

As I understand it, the OLPC system takes a photo of the laptop's owner at an early stage, and uses that in various UI elements to identify the child (e.g. the "neighbourhood" view).

Suggestion: this photo should also be displayed during startup, so that a teacher can work out who owns a laptop left behind in the classroom immediately, instead of needing to wait for the entire boot sequence.

It should also be displayed when/if the laptop is locked out due to a failure to contact the authentication server inside 21 days, or because it's been explicitly disabled due to theft.) This would allow a stray laptop to be reunited with its owner far easier, and/or make it simple for the police to ascertain that the person holding the laptop is not the owner.


That may well be the case.--[[User:216.194.7.250|216.194.7.250]] 11:39, 24 March 2007 (EDT)

== About internet access ==

I am very interested about the OLPC.
I am a pc programmer too and I am interested on programming for other plataforms, like the Playstation2, cellphones, and now, to the OLPC, too.
I know almost all about he OLPC, ecxept one thing:
What are the plans about the Internet access on the OLPC particulary on Brazil?

<i>You can find informations about this, in portuguese, at [http://www.dmu.com the DMU site]</i>


I think the platform is similar to all the other nations except the language is different. The subject matter is to reflect each nations individual lifestyle and customs. Brazil is also one of the first nations to receive the proto types.--[[User:216.194.7.250|216.194.7.250]] 11:54, 24 March 2007 (EDT)

== A little question ==

The user install other programs on the pc, like on a normal pc using linux?
If not, there is a way to run programs on the OLPC?
The programs that I am referring are other programs, developed by users, etc...
:The OLPC has a pretty small footprint. The OLPC Redhat distribution is very small, and has few program. There is an OLPC Redhat Development distribution which has a few more Linux programs, but it's still small. [[Sugar]] is the GUI interface, and has special [[activity]] programs. Activities are inherently networkable and sharable. -[[User:Jcfrench|Jeff]] 21:45, 6 March 2007 (EST)

The answer to your question is yes. You can install other programs on the OLPC, like on a normal PC running Linux.
The window system (Sugar) currently makes that hard, though someone is working on fixing that.

== Internet access ==

How is internet connectivity achieved?
:OLPC laptops talk to each other in an ad-hoc mesh network. Each school has a server which connects laptops on the mesh to the internet. -[[User:Jcfrench|Jeff]] 21:28, 9 March 2007 (EST)



== Which Unix-like Operating System? ==

I can find no link among section sub-headings to give me any clue as to where I find information about all the Operating Systems under consideration for this OLPC machine. It will be a Unix-like Operating System I am sure but that could be a Linux Distro, a version of FreeBSD or some other OS such as Minix. Or will this machine be a platform capable of running a wide range of Unix-like OS's?

:The OLPC group is developing an open-source laptop OS using Redhat Fedora Linux as the base from which to start. This software will be freely made available to the countries deploying the laptops. However, since the CPU is a standard AMD Geode and the entire design is open-source, a country is free to develop their own OS or to choose some other OS for their laptops. The OLPC group will provide support for the OS and software that we develop.

== Assistive Technology Software on the OLPC Laptop ==

In regards to accessibility, I think the 3 USB prots are a great idea. But what kind of assistive technology will be avaliable on the computer itself? Will synthesized speech, for example, have to be provided by an external synthesizer? Or, will a separate Nraille display and Braille keyboard have to be connected for a blind user to use the machine? Will the system have the necessary drivers built into the kernel or provided by external programs (such as Brltty)? What about support for mouse alternatives such as switches and head mice? Will the laptop be capable of playing sounds on events? I appologize for all the questions, but these are questions we are still trying to answer in mainstream operating systems.

The OLPC system has it's own set of rules and computing factors as mentioned on the many pages devoted to that subject.USB is also answered on this page. The answer to main stream operating systems would be Yes they have servers that are cross coded to allow them to give a limted out put via these servers. Will you beable to directly recive taged pages? Not at first but because from what has been said and the feed back they seem to work well and have few glitchs that will end up in
the main stream if any at all.--[[User:216.194.7.136|216.194.7.136]] 23:04, 3 April 2007 (EDT)

==A Question about site submission==

I was reading on one of the Wiki pages that you are looking for articles. But in the question and answer section you said the local communities will be adding things to the laptops internet mesh. Once the Laptops are received do you think it would be better to write to the government directly and submit sites based on simple graphics and texts that they can add them selves. I would like to submit but I wrote you people before and no one answered me and it is easier to get the Governments address and phone number . What do you think?


Well I think your idea sounds great! But you should hold off for right now in contacting the governments about submission ideas. If you look around the OLPC Wiki there are some ways you can make suggestions. But I am sure in the future once the program is off and running there will be ways to submit lessons and other suggestions to each OLPC location as well as to the OLPC program itself.

== Accessibility ==

I'm not sure if the information about accessibility on this WIKI answers the questions we have received about the laptop/program. So here goes:
Someone asked me if the device would work for children with disabilities? And if you been designing this device with disability accessibility in mind from the outset?
For instance, most persons with vision disability are not Braille readers so might need font enlarging capacity or some sort of audio outputs?
Likewise for children with fine motor skills disabilities (e.g., one hand or less than the usual number of fingers or dexterity impacted by other neurological damage) would the keyboard design work for them?
Likewise, for children with intellectual disabilities, is the interface usable for children who are not average?
We've heard that 10% of the world's population, or more than 600 million people, live with life altering disabilities, and two thirds of those persons are in developing countries (UN statistics). We assume many of these are children.
Would you give me a heads-up if you are designing, developing and fabricating this $100 laptop with disability accessibility needs in mind?
Thanks!

== Local version of SUGAR (particularly, Korea for me) ==
I want to make a Korean Version of SUGAR UI. I know the fact that currently you are making local versions for participating countries and, unfortunately, Korea is not one yet.

However, I think there is no reason to block writing local versions of SUGAR. Having one's own local version will help people persuade their governments to participate in OLPC.

Thanks.

Yes that is a valid point, but whose blocking it?
If the government is blocking this then there is really not a lot
you can do. They may have a good reason and later they will stop.
But that is if it's the Government.
You have to figure that part out first.

Sugar is designed to be easy to localize. It's a true pain to work on Sugar, though, as a programmer. If you want to localize it to the Korean language, I suggest going on the #sugar IRC channel on freenode.net and seeing if anyone there can tell you how to get started. They'd probably be happy with well written localization for the Korean language; it would shake out bugs in their Asian language support.







== Emulation-screen size control ==


I emulated Qemu on Fedora 5 but all I get is a full size version of the top 50% of the screen losing all the bottom icons and it will not seem to scroll down. How can I control screen size so that I view full screen?. Also How do I access the Shell or Konsole?.

== Data security regarding the camera, microphone and mesh network ==

Data on a laptop, that is in the hands of a child can never be called secure against malicious intruders, but that is not a great concern as long as the data consists basically of the childs homework.
But the OLPC XO has a microphone a camera and a mesh function (through the latter other people can observe its movements through the house). A malicious intruder might manage to remotely turn those devices on and gather a lot of private data on the family, including high risk data, like political opinions. This is a problem in the first world already, but in the third world, with its dictatorships or unstable democracies and often powerful criminal organizations the damage can be huge.
So to my question:
Does the XO have off switches for the aforementioned three critical devices and, if yes, are they physical (really cutting power off)? If they are not physical, how does the system prevent malicious software from turning them on?
Is there an accompanying paper, that explains the security precautions necessary for such a device to the child? --Steve

: Please refer to the [[Bitfrost]] specification, which goes into detail about our plans to address this potential threat. Also note that there will be LEDs that indicate that the camera and microphone are on physically attached to the power lines of those devices. --[[User:Walter|Walter]] 09:01, 21 April 2007 (EDT)
I was imprecise. Certainly there are features, to make an attack difficult in the xo as well as in any other system. But ways around will be found, and my question is, what if (and it WILL happen) the software layer of security is already broken and the computer "owned". What safely prevents the aforementioned devices from gathering data, when they are not explicitly used? --Steve

: I'll also try to be more precise: Please refer to [[OLPC_Bitfrost#P_MIC_CAM:_microphone_and_camera_protection]]. "The use of the camera and microphone require a special permission, requested at install-time as described in its chapter, for each program wishing to do so. This permission does not, however, allow a program to instantly turn on the camera and microphone. Instead, it merely lets the program ask the user to allow the camera or microphone (or both) to be turned on. This means that any benign programs which are taken over but haven't declared themselves as needing the camera or microphone cannot be used neither to turn on either, NOR to ask the user to do so!" --[[User:Walter|Walter]] 09:53, 21 April 2007 (EDT)
Thank you for your reply.
The LEDs are certainly a real gain of security. If permissions are a protection depends on the severity of the attack. If the attacker achieved kernel privileges, all protection measures, that come from the operating system are off. Since in unstable countries governments and their agents must be counted among the potential attackers, the signature exception is furthermore a major hole in the (by its software nature already imperfect) protection.

The simplest actually secure solution to the problem would be three good old-fashioned power switches, one before the camera, one before the microphone and one before the antennas. Steve

Typical scenario: A democratically elected president turns into a dictator and wants to spy on his people. Millions of microphones with communication gear are already in the households and, as a leftover from his old democratic days he has the cryptographic keys necessary to activate them. Steve

Now they said, that the XO will run 3$ Windows too. Not even Bitfrost is there when Windows is running and the project has no legal way to even see, where that OS has its weaknesses. This makes a physical solution to the microphone problem almost unavoidable. But since on-off switches are really dirt cheap when bought in masses, it should be easy to do. Steve

The LEDs in the B4 laptops turned out to be great for debugging all the times when the camera and mic were powered on when they shouldn't be by the software. They really work. Of course, that only tells you that the cam or the mic is in use; the LEDs don't provide a way to turn them off. A piece of tape, or a gooey bit of rice, will suffice to shut off the camera if it's turned on and you don't want it to be used. The microphone is a bit harder to shut off temporarily (if you've lost control of your software), since ambient sound penetrates the case. --gnu





== Spreadsheet Program ==

Shouldn´t a calculation program - some clone of EXCEL - be part of the standard software delivered with every computer ?
Remember, most of the kids are living in families that are peasants, and they might like to make accounts of what their "business" is producing, what resources are needed to produce it, and so on.





== Does Allowing Windows Violate A "Core" Principle? ==

Negroponte has said this is a "learning" project, not a laptop project.

One of the "core principles" you outline in this Wiki is the use of open source.

You state that the child should not be a "passive consumer" -- which means that he should have access to the source.

Now the news is reporting the XO will run Windows?

This seems like a contradiction.

Allowing closed source to ride on top of the OLPC makes it no more than a Trojan Horse...right?

:The Microsoft announcement has resulted in some confusion in the press. It is being suggested that because of the Microsoft announcement, OLPC will be switching from Linux to Windows. On the contrary, OLPC remains steadfast in its dedication to FOSS and has no plans to distribute Windows. However, we have consistant and public with our position that the spirit of openness and freedom; everyone, including software engineers at Microsoft, are welcome to develop for the machine. The fact that Microsoft has been making efforts to bring the price of Windows within reach of children in the developing world gives those children more choices. --[[User:Walter|Walter]] 04:11, 28 April 2007 (EDT)

== Will Limited Storage Impact Feeling Of Ownership? ==

I have been impressed by Seymor Papert's idea that the relationship that users have with their personal computers makes them more powerful. I also note that the storage limitations of the OLPC mean that some portion of the materials of an individual student are likely to be stored on the server. What I am curious about is how this will impact the student's sense of ownership and whether the software will be designed to mitigate this limitation by blurring the distinction of local/remote storage. I imagine that this might be done by something simple like establishing a virtual volume that contains the local and remote materials. Of course it may well be that this isn't an issue at all.

: The objective is to have the 'server' space transparently integrated into the 'user' space, so that accessing a resource (ie: a file) stored in the server will be transparent. For more info, you can read [[OLPC Human Interface Guidelines#Automatic Backup and Restore]] or [[OLPC Human Interface Guidelines#The Laptop Experience]] for a broader view. --[[User:Xavi|Xavi]] 22:46, 31 May 2007 (EDT)









== Cost, Distribution, Technical Support and Competition ==

It is apparent that in-country sponsor organizations must be involved to distribute and support the PC. These organizations may be governmental, or perhaps even charitable (aid) agencies.

OLPC should create "franchises" of a sort. The sponsoring organization will be responsible for providing a systems integration and technical support center (or centers) in which the PC will be assembled, tested, packaged and distributed; and from which limited technical support will be provided. The centers may also be responsible for establishing the WIFI networks required. The centers must be created by the sponsoring organization per OLPC specifications and should be supervised (from creation) by an OLPC employee. The centers will be funded and owned by the sponsoring organization, and all of the employees at the centers will be employed by the sponsoring organization --- except the OLPC supervisor. It's important to keep the OLPC supervisor independent of the sponsoring organization, since the OLPC supervisor will be responsible for auditing manufacturing and distribution per OLPC guidelines.

Expense in setting up the centers should be minimal for the sponsoring organization. I am happy to aid in the creation of specifications for centers. The specifications for each center will be similar to all others, with capacity being the only unique component of the basic equation. Network establishment for sponsoring organization's geography will also be similar to all others, with capacity and physical terrain being the unique components of the basic equation.


OLPC will establish credit/payment arrangements with each of the sponsoring organizations.

After account establishment, OLPC will send kits of PC materials to the centers for final assembly. The centers will perform top-level assembly only. Kits of parts will include, cases, power supplies, batteries, LCDs, unit packaging, etc. --- and perhaps a calculated spares supply based upon estimated (eventually, known) reliability of the PCs to ensure in-field functionality for 5 years. The centers would also be responsible for PC repairs and refurbishment, as well as network maintenance, to OLPC guidelines.

The sponsoring organization is responsible for distributing the PC per OLPC guidleines. Distribution expenses are borne by the centers.

The OLPC supervisor will audit the performance of the sponsoring organization. In the event that the sponsoring organization fails to meet OLPC standards, OLPC may stop shipments of PC parts to the center.

OLPC cost is reduced by transferring the labor costs of final assembly, test, packaging and distribution to the sponsoring organization, thus relieving the PC unit price of these costs. The countries most in need of the OLPC program have plentiful and inexpensive labor. Perhaps a penny or two per PC must be added to the PC cost so that OLPC can pay its center supervisors (and perhaps area - continent? - supervisors, auditing the center supervisors).
The creation of in-country infrastructure --- and local employment --- virtually assures loyalty and continuity of the OLPC program.

I can tell you that we make can even make the OLPC "franchise" work in the U.S. I can provide up to 50,000 employees who can assemble the PC in the U.S. --- legally --- for less than $1.00 per hour. Assuming OLPC program control in the U.S., these employees can even kit and ship the top-level parts to centers throughout the world.

I am aware that certain for-profit companies are threatening competition. Such competition is a serious threat to OLPC and its vision. If a commercial enterprise can thwart OLPC's vision, and cause OLPC to cease to exist --- PC prices will rise due the lack of competition.

The establishment of in-country partnerships with sponsoring organizations (probably governments) will be the only way that OLPC can manage competition from firms such as Intel.

dekedeac@bellsouth.net

:While it is possible to do assembly in-country in the future, in order to deliver the lowest-cost laptop in the first year, final assembly needs to be done close to where the some 800 parts in the laptop are manufactured. One needs to consider not just the total cost of final assembly, logistics, packaging, and shipping, but also the cost of logistical coordination of all the parts and their shipping for in-country final assembly, plus duties and capital equipment investment. OLPC and its manufacturing partners are happy to work with countries to explore a local-manufacturing option in future years and to create a phased plan for in-country manufacture now.

:OLPC does not want to limit in-country industrial development to only a few low-wage, low-skill, no-growth jobs such as assembling laptops, while the higher value-added, high-skill, high-growth jobs remain elsewhere. Focusing only on parts or system assembly is not sustainable economic promotion. Our commitment to open-source software and content allows rapid, viral growth of these industries in country, which dwarf the assembly-line manufacturing industry.

:Serving the OLPC “ecology” will create in-country business opportunities. There are numerous devices ranging from solar panels, generators, point-to-point wireless hardware to extend the network, novel, inexpensive educational accessories to be used with the laptop, and so on that can and will be invented in a grassroots, bottom-up fashion. Software is also an opportunity: systems such as the XO will enable both commercial and non-commercial software to be built to address needs in the majority of the world where computing has not been available due to lack of suitable computers and networks. --[[User:Walter|Walter]] 03:47, 16 June 2007 (EDT)

If we have learned nothing, we have indeed learned that simply dumping money, food --- or PCs --- into a needy geography does little long-term good for the intended clients. Don't send fish --- teach your clients how to fish. Without OLPC control of PC distribution, network creation and maintenance and repair/upgrade capabilities, the PCs you dump into the third world will disappear into oblivion.

The concept of client investment is a well-accepted method of creating the sense of ownership necessary to create and care for the in-country programs. The "cost of logistical coordination of all the parts and their shipping for in-country final assembly" bears exactly the same level of complexity as shipping the PCs. OLPC ships KITS of parts to produce X PCs --- not random shipments from various hardware manufacturers. In the unlikely event that there is a country on this earth that will not waive tariff or tax for humanitarian shipments, the kits of parts will be taxed at a much lower rate than the value-added PCs.

In-country assembly and support operations will be the ONLY way to keep your competitors at bay. Don't be naive. Intel can sell its PC for any price it choses. OLPC will lose a price war with any competitor that can produce and provide substantial hardware value a lower-than-market prices.

The in-country assembly plan works because labor rates will be directly proportional to each countries abilities to pay those rates. It's a perfect equation.

==B2-Friendly Software/Firmware Builds==
Its been a while since the '''olpc406_c11''' build came out and it doesn't seem (my observation) to bring out the best in the B2s. Are there any future releases that will be B2 friendly while serving the B3s and B4s? I'm asking because the XOs being tested in Nigeria are mostly all B2s (if I'm correct). --Ahmad 12:04, 4 July 2007 (EDT)

:There will be two new builds coming out in the coming days, both of which will be (largely) compatible with B2 hardware. One will be a variant of Build 406, but with the power management and suspend/resume in place. This should make a big difference in regard to usability in the school trials as the laptops should last a full school day on a single charge. The other build will be an experimental build that exposes a number of new features regarding the mesh and our model of sharing. It will also include the basic Journal functionality and the new ''tabbed'' Sugar UI. Initially, it may not be suitable for the school trials--the idea would be for a few machines in each school be set up with the new software so that the teachers and children can give us feedback. --[[User:Walter|Walter]] 16:21, 4 July 2007 (EDT)

== The Needy Children of the U.S.A. ==

To all of those people that want to donate
things to all of the children. Shouldn't we
think of all of our children in the states?

Stop & think of who is responsible of all the
teaching that the Americans are the enemy's.
with all of the organizations in this country
i would think that our country that a lot of
AMERICANS FOUGHT FOR & SO
MANY LOST THEIR LIVES FOR.THAT EVERYONE
THAT WANTS
TO START A DONATION &FUNDING TO SHOULD
START IN
THEIR COUNTRY THAT THEY LIVE IN.

STOP & THINK HOW MUCH DID
OUR COUNTRY DO FOR A
LOT OF OTHER COUNTRIES &
WHAT DID WE GET ION RETURN.

THE BIG CORPORATIONS SEND
ALL OF OUR WORK THEIR &
PUT HOW MANY PEOPLE ON THE OUT OF
WORK LIST.

JUST BECAUSE OF THE GREED OF BIG MONEY PEOPLE.
I THINK IF ANY MONEY IS SPENT IT SHOULD BE SPENT
IN OUR COUNTRY FIRST.THEN WHEN OUR CHILDREN HAVE
ALL OF THE LEARNING TOOLS THEN WE CAN HELP OTHER COUNTRIES.

NOW STOP & THINK WHO HELPED US ON SEPTEMBER 11!!!!!
WE NOW ARE INVOLVED IN A WAY IN A COUNTRY THAT
TEACHES THAT ALL AMERICANS SHOULD BE KILLED.
IS THAT THE KIND OF CHILDREN YOU WANT TO TEACH
MORE TO??
STOP & THINK WHAT YOUR FATHER & HIS FATHER
WOULD SAY!!!!!!!!!!!!!

SO PLEASE STOP & TEACH THOSE CHILDREN IN
OUR HOME COUNTRY.
ALSO THINK THAT HOW MANY CHILDREN DO WE HAVE
IN THIS COUNTRY FROM THE COUNTRIES YOU ARE
GIVING THESE THINGS TO.

WE NEED TO BUILD THE U.S.A. BACK TO THE
PROUD COUNTRY IT SHOULD BE.

There is a lot more i would like to
say but it all comes back to we should
help our Country first.

:OLPC is interested in helping children in ''all'' countries, including the United States. We have been in discussions with many governors and are discussing possible deployments in individual school districts. That said, I have two comments regarding your note: (1) OLPC has not been diverting any funds away from the United States into other countries; and (2) it is our belief that one of the roads to peace is making sure that every child in every country has an opportunity for learning. If we can help to eliminate ignorance, perhaps we can eliminate much of the underlying cause of hatred and violence. --[[User:Walter|Walter]] 18:11, 7 July 2007 (EDT)

== Support for application languages like Java? ==

Hi

I think this laptop could have huge potential as the hardware infrastructure for supporting scientific projects in the developing world. I´m a software engineer and I think it would be great to begin building custom applications that suited this particular kind of machine.

Does anyone know what programming languages or software development kits work with this? Dare I ask whether standard Java applications would work on this? Java is supposed to work on Linux based systems but I wonder whether the AWT works with the kind of display used in the laptop.

By the way, it would greatly help the developer community if we could get easier access to the laptops themselves. It could spawn all sorts of open source development projects to build software applications that were relevant to the groups who used them.

: You might want to take a look at [[Getting_started_programming#Operating_Environment | the Getting started programming page]]. The main programming environment supported on the laptop itself is Python, but you can also develop in Smalltalk in Squeak and Javascript in a browser-based activity. Note that Python is currently used for a variety of [http://www.python.org/about/success/#scientific scientific applications].

: Java is not in the official build, but I imagine Java and AWT can be made to work, since it works on other Linux/GTK systems (although performance may be poor, given the limited-resource environment). Running a full Java (or C/C++) SDK on the laptop may prove difficult, though... The easiest way to get a particular Java application on the laptop might be to compile it to an x86 binary on a more powerful system.

== How interact with the SUGAR operating system? ==

I've seen several answers to questions that indicate it is somehow possible to interact with Linux or the SUGAR interface, such as to install software, but in those instances there is no indication of how to do it.

Is that discussed anywhere? Is there some magic key combination (a la Windows) that allows interruption of the boot sequence at the right moment? Or, after booting up to the normal user interface, is there some magic way to escape to a Linux prompt and, if so, would it indeed look like Red Hat Linux? Or ... ?? - Bubba Bob
: One of the ways to interact is to use the terminal.

I have a niece who is in a one parent home struggling financially to make ends meet here in the USA,
she has 3 sons, 2, 11 and 12 years old. Her oldest son is in the 6th grade, she cannot afford the monthly fees for the internet, nor the cost of a computer for her oldest sons.
I think this is an unbelievable project!
I checked the website out just to see if I could purchase one for my nephews but I see from the reading material I cannot.

But, I sure would like the idea of prioritizing single family homes as the first to receive them, if you eventually allow state or county non-profits to buy them for individuals or schools or maybe the USA federal government, naaa that would take too long.

Anyway, if a non profit could be set up in South Carolina, I would be willing to be a volunteer.

Thank you.

There are third parties working on a BIOS for the machine but there is a fair amount of driver work required, e.g., DCON. As far as whether or not we would consider FreeDOS preinstalled, if there is sufficient demand for it and it enables us to meet our epistemological goals, then yes. --[[User:Walter|Walter]] 15:52, 23 September 2007 (EDT)

::::::DOS knows nothing of PCI, so the emulation code is not needed. DOS programs generally don't care either. DOS also doesn't need VESA, but many DOS programs do need it. DOS certainly needs a pile of BIOS calls, but these could be built right into FreeDOS. (in other words, hack FreeDOS to boot from OpenFirmware and supply its own BIOS crud) DOS also needs a text mode video screen; this would be difficult but possible.

::::One of the emulators is probably a better choice. It could even be wrapped up as a Sugar activity. If the emulators shipped with the OS itself, then one might be able to write DOS-based activities that are thin wrappers around DOS programs. Maybe there could be an easy way to share DOS disk images, much like TamTam projects can be shared. [[User:AlbertCahalan|AlbertCahalan]] 17:18, 23 September 2007 (EDT)

:FreeDOS should run just fine in Bochs on the AMD Geode chips being used. It would make more sense to leave the base machine alone and just run FreeDOS from a USB key containing Bochs and a disk image. That way you make the machine more useful because you aren't subtracting any of the core package and capabilities.

== Partnering Schools ==

My children visit a small primary school in Scotland, which is actively looking to find a partner school in the developing world. From talking to other parents, I believe I would be able find enough interest to purchase 30-40 OLPC laptops on your 'buy two - get one' scheme. Would it be possible to distribute the 'donated' laptops in one particular school and such create a community between the two schools?
: I don't know if it's possible to designate which country or school your "donated" laptops go to -- I doubt it, since that would increase the overhead of selling them to the public (and they're trying to keep the overhead very low). But what I suggest is that your Scottish school children find another school (anywhere in the world) which is also using the XO, and partner with that school. Nigeria might be a good candidate, since there would be less of a language barrier. -gnu
: Also, you can probably run your own "School Server" by getting an ordinary PC and downloading the appropriate server software that's published on this site. You'll need either a Marvell USB-based Mesh WiFi dongle (not yet available, but maybe soon), or you'll need to use one of the OLPC laptops as your mesh portal (gatewaying the school server onto the mesh, so the kids can access it). -gnu

== individual use in USA ==

If I "buy one - get one," I would give mine to my 6 year old grandson. Will he be able to network with kids around the world? Can the camera-mic be used to communicate with kids in Nigeria, Peru, etc?

Along the same lines, how will networking work outside the expected Mesh Network environment. For instance, can my 6 year old nephew use the WiFi hub in his home?
: Yes. -gnu

== How can I get an XO outside USA and Canada? ==

Why is the Give One, Get One program being restricted to the USA and Canada only? Lots of application/content developers in other countries will also be interested in buying an XO to work with. If you use the services of an international shipping company like DHL and accept credit card payment only, then it is really no more difficult to ship to other countries than to North America.

== using xo machine as music streamer ==

i am interested in doing the 2 for 1 program; I would like to know if the machine can be used to contually stream music off the internet (using rhapsody service)/ thank you
:The hardware is certainly capable of streaming music continually. As shipped, the XO can't play MP3 files, because of the MP3 patents; it uses the freely available Ogg codecs instead. But freely available MP3 software is widely available and would work on the laptop. There has been an effort by Real to port their pseudo-free Helix player to the Sugar XO user interface (called [[Watch and Listen]]). I don't know if it will stream anything from Rhapsody. Unfortunately, the Sugar implementation makes it hard to install common Linux GUI programs (like other music players) on the machine. -gnu

== Unlimited Give 1 Get 1 program ==

I think that OLPC has underestimated the general interest and strong demand for their laptops. I think that the Give 1 Get 1 program should run for now and forever, and not be just a limited 2 week engagement - there are far too many people in the US that want to provide a laptop for their children, like the laptop designed, and think that the Give 1 Get 1 program is perfect - they can get 1 for their children or relatives, and at the same time they can give 1 to another country that needs it. As many other people have requested in previous questions and comments, they wanted the ability to directly purchase the laptop or somehow provide it to their communities in the US. The Give 1 Get 1 program helps to fill BOTH needs simultaneously. Do not just run this program for the limited time. You accidently hit upon what can push this program into overdrive. As you have found, Governments will never shovel out cash for anything. BUT private individuals will - if they can get something for their efforts as well.
: I don't speak for OLPC, but my guess is that they're going to gather up all the orders over that two-week period and then order and ship that number of laptops, so that they're ordering thousands at once for efficiency, rather than one or two at a time. I presume that if the first burst of orders doesn't satisfy the demand, they will be amenable to doing something similar every few months. (Of course, anyone who wants to invest in buying a bunch of XO's during that two weeks is free to sell them to others -- for whatever price they can get -- after the order period closes. So an enterprising person could make some money selling them for e.g. $500 during times OLPC is unwilling to do so. And people could then get them in small quantities at any time.) --gnu

== access to email & the internet ==

Will access to email and the internet be available if a wireless connection is available?

: I've seen the XOs working at a conference using the convention center's commodity wireless connection, so I believe the answer is "yes". Of course, such access will be easiest if you are using webmail and everything you need online can be accessed via Firefox, since that is the main internet application shipping with the laptops. Running other internet programs may be more difficult, depending on a number of factors (whether someone has made an XO version of it, whether it is bundled for Fedora, whether it is ported to Linux, how many resources it uses, etc.). &mdash;[[User:Leejc|Joe]] 20:19, 24 September 2007 (EDT)
:: The browser is not Firefox (unfortunately); it uses some of the guts of Firefox but trashes the user interface. So you can only view one web page at a time, for example. And there is no email client at all. However, there's a rumor about [[Installing Debian as an upgrade]] on the machine, which when perfected, would free it from many of its software limitations. --gnu
:::While we haven't exposed all of the Firefox features (yet), it is essentially a fully featured web browser. Contrary to the assertion above, you can have multiple webpages open at once and multiple windows when spawned by a page. Other options include loading Opera on the laptop. Switching to Debian won't make much difference. If you are so inclined, you can run X Windows without the Sugar UI and use a standard Firefox, but you will miss out on many of the Sugar features, such as mesh collaboration and the Journal. --[[User:Walter|Walter]] 23:21, 24 September 2007 (EDT)

== Other software ==

Will you be able to load other software packages (small) on OLPC? For example data logger or GPS software?

:OLPC is physically capable of loading all kinds of Linux software, and some of it can be run in a terminal window, or by replacing the Sugar UI with a more capable GUI. There are DRM modules that some OLPCs will ship with, that prevent installation of new software. I hope and pray that these will be disabled on OLPCs that are sold under the "Buy 2 Get 1" program. In theory, "developer keys" that would disable all the DRM will be available to any OLPC owner, but OLPC has not actually created a mechanism for getting one yet. --gnu

just heard about the buy 1 give 1 program, which sounds great, but i wonder if there aren't many in north america who would appreciate a kid-friendly computing environment for whom $400 is a bit much to spend, especially if they already have access to conventional hardware.

i haven't analyzed the pros and cons thoroughly but the following qestion occurs to me:

would it be practical to create a knoppix-style live CD version of the OLPC environment (or a useful subset) that would run on generic hardware and use it as a fund raising device? an automated site could permit downloading disk images and assertively request a donation . (as it's open source you can't charge a licensing fee, but requesting a donation is probably OK.)

donations could then be used to subsidize the cost of distributing the complete machines where they are needed.

many folks already have kid-unfriendly PCs at home. others have access to hand-me down or refurbished hardware incapable of hosting contemporary grown-up computing environments but that would probably work OK with the OLPC software. making a $25-$50 donation and getting an OLPC-like environment on disk might be an easier sell in such cases than a $400 expenditure.

as a side benefit, such a project might permit experimenting with expanding the target audience for the software. there are folks other than young children who might benefit from a more approachable computer. (the elderly, adults with special needs, etc.) frankly, in some respects this may be a better general purpose computing environment than some of the fatter mainstream ones.

also, getting the software in broader use in developed countries might preclude any stigma connected with the idea of a special product for the poor. it could change the OLPC hardware from an specialty computing system just for the poor to a specialty platform for hosting a software environment that is popular among the affluent.

(as the software is open source presumably it's already possible for somebody to do this independantly and perhaps somebody will. this might be benfit the project by popularizing the software, but it wouldn't help the project raise funds. might be good to get there first.)

:Right, poverty is right here in the USA. $399 is no good for the kids of a West Virginia coal miner or truck stop waitress. These kids often have just one practical option for getting out of poverty: join the military. $100 might work, barely.



== What power source will come with the November Give one get one XO for the purchaser? ==

What Power source will come with the xo laptop for the purchaser during this November's give one get one? WIll it be an AC adaptor and/or a pull cord?
Thanks,
Greg
:AC adaptor.

== Distribution over missionaries? ==

The project wants the country governments for the buying and distribution of the XO to their students.
But is there a possibility for missions (Christian) to buy laptops for their development projects?
In many countries missions found schools and start educational programs. Are there possibilities for missions to get involved into the distribution of the XOs?
The "give 1 get 1"-program is not an opportunity for the missions, because they can't afford the doubled price.
I think missions could be a great distributor, because they go with schools where governments aren't.

:We are open to discussions with NGOs.



== Mono libraries on OLPC for activity developped on MonoDevelop ==

Hi,

I will make an activity for olpc, but i want to developpe on c# with monoDevelop how can use gtk librairies for the Gui of my application.

It is possible to install the Mono librairies on the fedora core how works Sugar ? and it is possible to execute c# code on the olpc

Thank you for your answer.

:It is possible, but we are trying to keep the number of dependencies minimal in order to keep the footprint small. Is there some reason Python anf pygtk cannot work for you? --[[User:Walter|Walter]] 16:13, 27 September 2007 (EDT)


thanks.
I carry out a work of diploma and the goal of this work is to make the portage of already existing .net code on sugar linux as an activity. I have also the possiblity to re-code all in python but the portage would get the possibility to the .net developer to create activities for olpc and to make this portage I absolutely need the framework .net on olpc and Mono makes it possible. --[[User:Cihan|Cihan]] 09:53, 28 September 2007 (EDT)

Hi, I migrate an existing application (a simple game) to the OLPC platform.
To integrate the GTK# with sugar environment I start to write a Sugar assembly that permit to create a new main window integrated with the sugar shell.
I hope to release my simple "prof-of-concept" code as soon as possible.
I try to put all my code in a single .xo bundle including the mono runtime so nothing is necessary to install on the OLPC.

== Is there a way to find local developers/testers with the physical units? ==

I hope to participate in the Give 1 Get 1 program. I would like to find someone in my local area to test (read as 'play with') the mesh concept in real equipment. Emulation is neat, but not ''real''. Is there any plans to provide a place on the Wiki for finding fellow OLPC'ers for testing, development, etc? Or have a I completely overlooked an existing feature of the Wiki?

== word processor ==

I am not a computer person, so this might be a dumb question, but it is one that confuses me. Say I use the word processor on this laptop to write a document. Now say that I send the document via e-mail to someone with a conventional computer. Before I e-mailed it, would I have to convert my document to Word? If so, how would I do this? If not, can it still be done? Or can conventional computers read the document no problem? Thanks a bunch for answering.

:The XO laptop uses AbiWord as its word processor. If the person receiving a document cannot open it using their normal PC software, AbiWord is available for many platforms and many languages from [http://www.abisource.com/ this site].

My name is Steve and I would like to know if you can set up for a classroom to network from a teachers to 30 kids for testing in the 2nd grade, to help our teachers and children learn, and to help teachers find and help slower learning kids and bring them up to speed?

Please get back to me on this;
Thank you, Steve

:Not sure what you are asking. We've been working in classrooms of up to 80 children. We are certainly interested in children and teachers learning and believe that the laptop will give them that opportunity. In regard to "slower learning kids", often times "slower" is really a matter of needing a different path to approach a problem; one nice thing about computers is that they offer many different venues for engagement. --[[User:Walter|Walter]] 10:06, 1 October 2007 (EDT)



== Is purchase of an XO by the relatively wealthy unethical? ==

I am very attracted by the simplicity and rugged design of the XO but as a citizen of arguably the wealthiest nation in the world is it an ethical choice for me to own one? I travel and commute by motorcycle so the ruggedness and simplicity of the XO is perfect for my uses as my only computer.

My misgivings about owning an XO come from the following thoughts. The production numbers of the XO are limited therefore would it be more ethical for me to spend $200.00 (US) for a used laptop and give another $200.00 to provide an XO for a child? By doing this I am keeping a used machine out of the bin longer and providing a purpose built machine for it's intended user.

I am not passing or implying judgment on those in wealthy nations that purchase one but asking an open question. Because the XO is available and the wealthy can afford them should they when the available numbers are relatively low and therefore the supply to the intended users is reduced by their purchase?

:The more production, the lower the per-unit cost. Ignoring environmental effects and short-term supply issues, purchasing a few million for your local landfill might ultimately help kids by getting the per-unit cost down closer to $100. :-)

:Of course the better solution for wealthy people is to [http://xogiving.org/ Give 1, Get 1] and then donate money for additional laptops to go to kids. If you have PayPal, you can donate money now on the Give 1, Get 1 site. Or, if you want to write a cheque, then send it to the address on the [http://laptopfoundation.org/participate/ One Laptop Per Child Foundation] page.



== Payment plans? for low income ==

Will you take $40.00 a month for ten or even twelve months? To get the buy 1 give 1 program? My daughter and I live in poverty,but can pay $40 a month for this most wonderful program. I want to help with the success of 'One laptop per child' program. What can I do? Please reply.

:OLPC does not yet have this functionality on its website. We are working with our credit card vendors and hope to introduce it in the next couple of months.



== United States ==

I think the idea of distributing these laptops to the countries you have listed is a great idea! However, what about the parents here that can not afford to buy laptops for their children. I am a single parent and work two jobs and then after working 10 hrs and cooking/cleaning we then have to go to the library so my son can finish doing his homework on their computers at 10:00 at NIGHT!. Why isn't our goverment involved in this project? Why isn't our goverment taking care of it's own? people!

== Printing ==

Will you be able to Print from the OLPC

== G1G1 for school servers too? ==

Schools in the USA also need servers.

== Colorblindness ==

I'm colour blind, and it is likely that any sons I have will be too.

How will they be able to fully access the Sugar interface?

For example, will my son be able to tell how much battery charge is left? Will my son be able to distinguish his friends' icons on the mesh map?

Red-green colour vision deficiencies affect around one in twelve caucasian europid males, although other types of colour vision deficiencies affect tiny numbers of all races and sexes.

: The XO is unique in that it has both a backlit color mode and a sunlight-readable monochrome mode. The interface is being designed so that it will be usable in both modes; for instance, colors are being chosen both for their difference in value as well as their difference in hue, so that they are distinguishable in both modes. Hopefully this should go a long way in making the laptop easier for colorblind people to use. ''(See also [[OLPC_Human_Interface_Guidelines/The_Sugar_Interface/Colors | Colors in the OLPC Human Interface Guidelines]])''

: Also, there are alternate ways to identify users beyond the color schemes; since there are only 200-some color pairs, some duplicates within a school are [http://en.wikipedia.org/wiki/Birthday_paradox inevitable]. &mdash;[[User:Leejc|Joe]] 15:53, 5 October 2007 (EDT)

Can the XO Laptop print a printer? If so, does it print to all printers or just some?



== Give 1 Get 1 for a U.S. school? ==

If I were able to convince enough local parents and other donors to raise $400 times the number of students in our kindergarten, could we participate as a group in the Give 1 Get 1 program, thereby equipping all our local students entering elementary school and an equal number of children in some other part of the world? If we were to do so, could the OLPC provide us with contact information for a corresponding class in some other part of the world, so the school children here and there could engage in cross-cultural dialog as a mutual learning experience?

== Do you need help on marketing in Europe? ==

I am a marketing and communications professional and see many ways on how XO could become a great offer on the children's and educational market whilst helping children and schools in other regions get equipped.

== Will we be able to purchase a Pull-Cord Generator and/or Solar Cell for the Give 1 Get 1 laptop? ==

You have answered that the G1G1 laptop will come with an AC adapter.
The unique (and amazing) capabilities for manual and solar power are
something I would like for my "keep 1" laptop.
Will there be a way for us to obtain these OLPC laptop accessories?
Additional cost would be acceptable.

== will olpc work on a open wifi network in a bookstore ==

I realize that OLPC uses 802.11s and that is based on 802.11b/g.

Will it be able to communicate on an open wifi network that is common
in the better bookstores and coffee shop, colleges etc.

:It does normal networking too.

== Link between the two give 1 get 1 laptops ? ==

Wouldn't it be great to have some kind of link between the laptop I get and the laptop I give?

The kid getting the laptop I give could write me an email, maybe send a picture.
This way there could be great contacts with people who otherwise would or could never communicate with each other.
That would really broaden the mind of me and of the kid, too.

I know this should be difficult to accomplish, but think about the possibilities.
Think about how happy both the donator and the donatee would feel to have such a bond.
Think about how many many people in the richer countries would gladly give money,
because they can really really see where their money is going.

Since all laptops surely have some unique number or sth. like that, it should be doable.

Ok, so my question is, could there be such a link between two OLPC?

== Wireless on/off switch? ==

Does the X0 have a hardware option to turn the wireless off and on? If so, what key(s) are used? If not, is there a simple software option?

Zane

== Multiple users per laptop? ==

I know the philosophy is "One Laptop *PER CHILD*". However, we were wondering about getting just two or three XO's for our preschool, and having the kids share. Is that feasible? Would all the kids have to share the same file space, or is it possible (with user profiles, or separate flash memory cards) for them to have their own space?

== SD card size? ==

How large an sd card can the xo use?

== dial-up ==

sorry if I'm dumb. If I do the "buy one, give one" thing, and I don't have wireless access, will I be able to access the internet via dial-up?

:You can use a USB to serial (RS-232) converter to connect to a modem for dial-up access. [[User:Chm|Chris]] 21:25, 14 October 2007 (EDT)

== Boot Time ==

As of this date, October 12, 2007, as OLPC prepares to undergo full production, what is the boot time of the XO?

== Donating the income of free ad space ==

I would like to use some free space on my site to place ads. I want to let the income of these ads be donated to the OLPC project. Is there a possibility for me to ensure that the advertisers paid for their ads by donating to your project, without transferring the money to my account first?

:Thank you for your interest in donating to OLPC. We recommend that you transfer the money through your account. First, it will allow you to ensure proper credit for a possible charitable donation (please make any donations payable to the OLPC Foundation). Second, tracking and confirm third party payments would introduce an overhead that our small, already multi-tasking team can not take on.

== One Laptop in America ==

It would be nice if we could concern ourselves with providing children in America before we worry about everyone else. My wife is a teacher and cannot even get a single computer in her classroom much less a laptop for every child. Why can't we fix this problem first. I saw the report on Dateline (I think that was the show), and the question was asked if we can purchase them for Americans, and the response was we have to buy two. One for us, and one for someone in another country. Are you kidding me?

== Give 1, Get 1 - warranty/support ==

For people participating in the Give 1, Get 1 program, how will warranty and support issues be handled? As I understand it, other countries buying XOs for students will buy spares and handle maintenance and repairs themselves. What will be the warranty period for the US purchased XO systems, and will there be some type of mail-in or depot exchange/repair program available (possibly through Quanta)?

== is there a scope to filter age-specific or grade-specific information ==


I am a parent of 7yr old and a teacher educator.
I was going through the library grid. The info there is quite useful for children(and educators). I am wondering whether it would be possible to make it in to auto-capsules that are age-appropriate and adequate? For example, I was going through module on animals,the info is vast and a child of say age 7-8 may not require all that is there, may be he/she would be quite thrilled to get some exciting bits of it to begin with. How we can filter? of course one way is through teacher intervention, but typical parental tendency would be to make available all that is out there on the wiki. I would be keen to know any such efforts are made in this direction to sort the info grade wise/age wise?
thanks

== Making a donation from a group ==

As part of a discussion in my Bus Adm 230 Introduction to Information Systems lectures, I talk about the digital divide. As part of this discussion I mentioned projects designed to help bridge this chasm - and of course - talked about the OLPC program.

I have collected over $100 dollars from my students for your project! I will add enough money to bring the total up to $200 - enough to provide a child with an XO laptop. I would like to know the best way to donate this money in the name of my class.


I am a volunteer at an organization that implements the OLPC project in Honduras. I am trying to help in different areas and one of them is to create documentation that will guide the end users of the program. This documentation is aided with descriptive images and one of them, which I need from you is the one that has the diagram of the structure of the OLPC project (technology oriented). I was looking at some links that show this diagram but I can not find it anymore. It has an oval of the acronym OLPC in the center and it branches out to the left with technology and to the right with outreach and education. It will be of great help if you can provide me with such an image.
Thank you for giving my students the opportunity to make a difference!


Thank you,
== Antennas , plugs ==


Alfonso Calero (a_bellorin@hotmail.com)
why do the antennas have to be sticking out, as it makes them easily breakable / fragile ? Couldn’t you put them alongside the screen like it is done on other laptops?
Although it gives it a fun look, it probably cost more if they can resist real life bending and tearing? What about dust /sand in the plugs, are they isolated from the rest of the case? Are these plugs safe if a child put’s in a paper clip?


== Alvin, mesh ==
Hope I don't offend anyone in asking, trivial questions.


I have a couple of XO's with me. I would like to change the network protocols and analyze the results.
: I don't know much about the decisions behind the antennas, but there are several facts that may help answer your questions: The antennas serve double duty; they both provide wireless networking and cover the plugs to provide some protection against dust. Unlike typical laptops, the XO has almost all of its electronics in the screen portion (only the keyboard and battery are in the base), so having an antenna around the edge of the screen might not have been an option due to interference. If I recall correctly from when I last saw an XO, the antennas are rubberized and quite rugged; this is apparently a recent design change in reaction to [[OLPC_Peru/Arahuay#Arahuay:_the_Technical_side | field tests]]. [[:Image:DSCN0374.jpg | This photo]] shows that the plugs are directly on the motherboard, not really isolated at all, but they may still be adequate for keeping out dust. According to the [[Hardware_specification#Regulatory_requirements | hardware specification]], the laptop conforms to [http://www.astm.org/SNEWS/MARCH_2003/lawrence_mar03.html child toy safety standards], among others, which hopefully test for the safety of the ports as well. &mdash;[[User:Leejc|Joe]] 14:04, 17 October 2007 (EDT)


I would like to know where is the mesh protocol located on the XO? From where can I change the protocols?
== Will the OLPC be able to boot something like PUPPYOS via a USB stick? ==


Thanks in advance.
Before I consider the purchase of two OLPC laptops, I would like to verify that the hardware will support booting Linux via USB flash devices. I know PuppyLinux was unfortunately quickly dismissed as a possible candidate to run on the OLPC hardware; however, since the AMD Geode is a x86 processor, I am in hopes I can boot PuppyLinux from USB attached devices, IE... USB Flash, Compact flash using USB adapter, hard drive/cdrom/dvdrom using sata/ide-to-USB adapter, etc.. Has anyone on the development team tried to boot any of the later PuppyOS releases on the current OLPC hardware? If so, how did it work?
:Hello. The mesh protocol is only available on the XO-1 model. Confirm you have an OLPC XO-1 model first. The OLPC XO-1.5, XO-1.75 and XO-4 models do not have mesh. Next, the mesh is implemented inside the wireless module firmware, with some small functions in the Linux kernel. Because it is in the firmware, you cannot practically change the protocol. --[[User:Quozl|Quozl]] 03:44, 8 April 2013 (UTC)


::Hello Again thanks for a quick response earlier. Yes I have XO-1. I have some more Questions. Is there any way I can change the protocols in XO-1. Will I be able to change the Network Protocol Parameters? If Yes than how? Thanks in advance.
Thanks Very Much In Advance

Ron


:::It depends on which protocol you wish to change. No, the mesh physical protocol cannot be changed.

::::Thanks for the information earlier. My interest is in the routing. I am doing a research on the mesh protocols. Some more questions to answer please. (1) Is the routing (and the corresponding layer) is part of the firmware too? (2) Which application layer software (GUI..etc) do they include to enable students to create links and task on the mesh? Thanks in advance.
what will the laptop come with if I get one from the give one get one offer?


:::::It is of historic use, I guess. XO-1 mesh implementation was not continued beyond XO-1. Our XO-1.5, XO-1.75, and XO-4 models use ad-hoc rather than mesh. To answer your questions: (1) Routing on the mesh is entirely handled by the wireless module firmware. It is an implementation of IEEE 802.11s draft. It is incompatible with IEEE 802.11s final. (2) Sequence is: user selects Sugar network view, then clicks on a Mesh icon. Sugar sends mesh request command to Network Manager daemon. Network manager sends command to kernel. Kernel sends command to wireless module via USB. Reply cascades back up the stack, and the Mesh icon is changed to show it is selected. User starts a Sugar activity and enables sharing. Activity uses multicast UDP to advise activity is available for sharing. Other nodes on the mesh receive the UDP and update their network view. --[[User:Quozl|Quozl]] 03:39, 9 April 2013 (UTC).
== Give 1: Get One program --> how to run another OS on my olpc ==


::::::Thanks for the information earlier. Will I be able to get a chance to edit wireless module firmware? thanks
While I am fascinated to try the sugar UI paradigm, I feel that I may wish to run a different light linux distro on an olpc that I get through the "Give 1: Get 1" program in order to work with a broader and more current selection of packages. This raises a number of questions which I haven't been able to find answers for:


:::::::Chance: 0.1% Because it is in the firmware, you cannot practically change the mesh protocol. The firmware is the property of Marvell. The source code is not public. The firmware is in the file usb8388.bin which is stored on the laptop. The file is sent to the wireless module after power is turned on. There is no public documentation for the ARM and baseband processor on the module, and these chips are from a silicon design around 2005, and probably no longer available. The module is soldered to the main board. --[[User:Quozl|Quozl]] 04:58, 9 April 2013 (UTC)
*What distros other than the stock image will install easily on the OLPC? I know fedora is related to the OLPC stock image, but is fedora light enough? What about DSL or another light distro?
*What drivers and other software may need to be hand added to these distros to take advantage of the networking and display optimizations of the XO?
*Does the XO hardware have the capability to work with more standard network topologies and use standards such as WPA?


::::::::Hello, I have some more questions. The network is usually organised in a few layers, traditionally in seven. The lowest layer is the physical layer. That is indeed firmware and cannot be edited. Above that we have the data link, network, and transport layer. Routing will happen in one of these layers, usually in the network, sometimes in the data link layer. Question is: where is the routing taking place for the OLPC XO-1 and the other versions of OLPC XO (like XO-1.5 ..etc). thanks.
: "Easily" is a relative term, and even more so when combined with the words "installing Linux". :) There is a page on the wiki that tells how to [[Installing_Debian_as_an_upgrade | install a fairly vanilla Debian]] on the OLPC (and there's also one for [[installing Fedora Core]], but that is quite old and uses a custom image). Given that Debian goes on fairly easily (where "easily" requires command-line work, a USB key, and an additional Debian machine), I imagine other Linux distributions could be made to work as well. I have seen the XO running off of commodity 802.11b wireless networking, and I understand it also [[USB_ethernet_adaptors | works with ethernet if you have a USB adapter (but not just any adapter will work)]]. &mdash;[[User:Leejc|Joe]] 15:01, 23 October 2007 (EDT)


:::::::::We use TCP/IP for networking on OLPC XO, and TCP/IP is not based on a seven layer model. Wikipedia has an [http://en.wikipedia.org/wiki/Internet_protocol_suite#OSI_and_TCP.2FIP_layering_differences article that describes OSI and TCP/IP layering differences]. Routing happens in as many layers as are required by the definition of those layers, not only one. There are two layers that contain routing for XO-1, and one for XO-1.5, XO-1.75, and XO-4. The mesh on XO-1 automatically maintains a list of mesh nodes in the wireless module, considered to be physical routing. The other layer is TCP/IP routing, which is provided by Linux, and is not unique to OLPC XO, so it would be redundant to describe it here. Look for a text that describes TCP/IP. --[[User:Quozl|Quozl]] 01:32, 10 April 2013 (UTC)

My OLPC stucked off after starting up and please also guide me that from where i can get new charger for my olpc?

Question

We are planning to help OPLC but we need to check the Financial Statements of the organization. Does somebody know where can we get this information?

From OLPC directly, or the government or other regulators. I don't think you should rely on what contributors to a community Wiki might tell you ... that's not a rigorous method. --Quozl 03:23, 13 February 2012 (UTC)

Question

I turned on my OLPC but it didn't show anything.What do I do?

Check out Keyboard freeze fix for os 650-656 it might be your problem. Hard to say, unless you can give some more information, like when you last used the XO, whether the power indicator turns on, whether the display backlight turns on. --Quozl 21:04, 30 August 2011 (UTC)

how do download windows xp on to my olpc xo and how do you access your downloads

There is no way to get Windows XP for your individual OLPC. Microsoft does not make it available to individuals, and OLPC has nothing to do with that.

How to access your downloads?

If you download things on the OLPC, they should show up in the Journal, which is one of the Activities that's always running. It looks like a little spiral notebook. You can also open the journal by pressing the "magnifying glass" icon in the upper-left hand part of the keyboard.

how do you start your downloads

I downloaded adobe flash player but i still can't watch my videos i know you go to journal and the file and click start but it doesn't work.

See Adobe Flash for details. Mariano 06:44, 8 December 2009 (UTC)

your disk is full

What should i do if i go to my record activity and it says my disk is full?

You should open your Journal and remove large files or activities. Mariano 06:44, 8 December 2009 (UTC)

== It seems that with the new built (8.2) in the XO the existing Scratch files are difficult to copy into a USB. I can't use the function "save as" or even copy them from the terminal.

How do I chat with other people in the world?

My xo is hooked up to the internet but I still don't know how to chat with other people in the world could you tell me how please?

First connect to a Jabber server or your local school network. Then you can see other people on your network and will be able to chat with them.
You can also download XoIRC and chat with people using that activity. 02:34, 17 December 2009 (UTC)

Two activities

hey i've got 2 questions 1. first of all why won't my eye chat open even if i have downloaded it 2. second how can i read e-books on my olpc oh and one more question: can i contact the child who got the other laptop after i had paid for mine? thanks

Thanks for your questions. Sorry, I don't know what eye chat is. E-books in various formats can be read using the Read activity, and there are new E-book reader programs on http://activities.sugarlabs.org/ . No, you can't contact the child who got the other laptop. -- Quozl 22:46, 26 July 2010 (UTC)

How does the Log Viewer work?

Dear Sir/Madam,

As a part of an evaluation project we are trying to determine what activities are being used by the children, and for this reason we would like to know exactly how does the log viewer work. The journal presents the problem that activities may be erased by the children, therefore not providing a complete picture. So my questions are, what does the log viewer exactly show? Does it show all the activities used by the children? Does it only show errors in activities used by the children and if so what type of errors? Do you think the log-files can be used to determine what activities are the children using or the information won't be reliable towards that purpose?

Also, is it possible to recover erased activities from the journal?

Thank you for your help!

how to repair olpc

hi olpc i am call placide and my olpc can not switch on now but the screen can switch on but does not mark any thing so it looks like has virus or it has corrupted so i would like to know how can i repair it and what can use to repair it please i need help

This can happen if you hold down the rotate button when you turn it on. Please try this: remove the battery, disconnect the cable, wait 10 seconds, put the battery back in, press the power button. The laptop should start. If it does not, then it may need repair. -- Quozl 04:14, 25 October 2010 (UTC)

Skype microphone issue

I have been using Skype on my XO1 with ver. 656 without problems but after updating to ver. 802 and re-installing Skype using the directions given on http://wiki.laptop.org/go/Skype (Standard) the sound of the microphone is garbled, when placing a test call, even though it is clear when recording in terminal mode by using arecord and aplay. I have tried several settings in Alsamixer and Skype but without getting any change or improvement. Is there a patch or fix for this problem. Updating to ver. 852 did not work as Skype will not install on the 852 version on my XO1. Note: I re-installed 802 and Skype several times and in several different executions following posts under OLPC but always with the same result. Placing a test call in Skype gives a playback with garbled microphone sounds like two voices overlapping each other and then shorting out.

Hola..

seria muy ueno si tendria para algunos alumnos mas avanzados la posibilidad de una de las nuevas plaquetas minis como para subir a 8 gb el disco solido , pero me parece que la memoria de 1 gb ya viene incorporada en el mother . y no tiene ningun slot

hoy dia los costos bajando y ojala en tiempos proximos alcancen un precio infimo como para poder incorporar mas almacenamiento.

Problem updating from 656 and mouse freeze

Hello I am having trouble updating from the 656 system and now my mouse and keyboard has frozen. Can you please advise me. Thank you. -- heather

Hello Heather. What have you upgraded to? Does the mouse and keyboard remain frozen if you remove the power adapter and battery and put them back in? Write to help@laptop.org (our OLPC technical staff) if you'd prefer e-mail. --Quozl 02:01, 3 January 2011 (UTC)
Hello
I tried using the email but only got a generic response. To answer your questions:
- I was trying to upgrade to the 10.1.2. I tried with the USB method and got the grey grid with a message underneath, something about NAND and size.
- I then tried to update in terminal using all the various wordings proposed. That did not work either. I left the machine for a day or so and when I turned it back on the mouse and keyboard were frozen. When it lit up with the clock, it would go to a black screen with some text at about a quarter of the way round and then, before I could read it, it would go back to loading. I tried turning the machine on holding the O key which made the black text screen disappear but did not fix the freeze. I tried removing all power. I tried turning the machine on holding the rotate button. Nothing has worked yet. I'm really excited that you are responding to me and look forward to finding a solution.
Take care. -- heather
Did the generic mail response give you a tracking number? If so, let me know what it was. That will help us mark it as being handled.
The grey grid sounds good, the message does not. There may be a fault in the laptop, or a problem with the download or preparation of the USB drive.
The grey grid occurs with an install of 10.1.2, so I'm presuming you are wanting to do an install, which wipes all data off the laptop. If so, please try again and this time check that you are following the install instructions below and tell me exactly what the message about the NAND says.
Regarding the update in terminal, I don't think you should try that again, because having started the install the contents of the internal storage is undefined, and the results may be unpredictable. The mouse and keyboard freeze is common; it happens if the laptop runs out of memory. We didn't test update from 656 and it may not work.
Feel free to send me an e-mail at quozl@laptop.org if you like. --Quozl 22:24, 4 January 2011 (UTC)


How to install signed build os852 of release 10.1.2 on XO-1.

The build is installed to the internal NAND flash device. You will need a USB drive of at least 1 GB capacity, but only for the duration of the installation.

ALL USER DATA WILL BE ERASED FROM THE LAPTOP!

  • Prepare the USB drive:
    • Download os852.img,
    • Save the file to the top directory of the USB drive,
    • Download os852.img.fs.zip,
    • Save the file to the top directory of the same USB drive,
    • Rename the file to fs.zip, (removing the os852.img part of the name),
    • Check the USB drive contains at least the two files fs.zip and os852.img.
  • Prepare the laptop:
    • Make a copy of any data you wish to keep,
    • Check the battery is inserted and locked,
    • Check that the power cord is in place and the battery indicator is green,
    • Turn off the laptop, unless it is already off,
    • Insert the USB drive into any USB port on the laptop,
  • Start installing:
    • Hold down all four game keys (see this in pictures),
    • Turn on the laptop,
    • Wait for the message Release the game keys to continue,
    • Release the game keys.

Installation progress will be displayed. Green colour will fill yellow blocks. It will take about five minutes. Once finished, the laptop will reboot automatically. Remove the USB drive during or after the reboot. The USB drive can be used on other laptops.

If you see a message Boot failed then either:

  • the USB drive has not been properly prepared, or;
  • the firmware is out of date and should be updated (see Firmware).

Wi-Fi WAPs not visible in Neighborhood View

I installed the 10.1.3 version to my XO-1. Initially everything was fine including the WAP icons. Now I am only seeing the MESH target icons. I know the access points are working in several locations including m home one but still nothing but MESH is visible in the Neighbothood View. How can I fix this, short of trying a reinstall of 10.1.3?

This will happen if automatic power management is enabled, which is the default, and the laptop is not kept awake for at least a minute. This is in the release notes. Try turning off automatic power management in the control panel. If that does not change things, please use Open Firmware to check the wireless card. Obtain the Ok prompt, and type scan-wifi then press return. This scans for wireless access points by turning on the radio receiver in the wireless card. Doing this test in Open Firmware is useful, because it excludes the 10.1.3 software entirely. If it doesn't show any access points, then there's no chance that 10.1.3 will. If it does show them, but 10.1.3 does not, then at least we know the problem is not hardware. Let us know how you go, because based on this test there are very different further tests to make. --Quozl 23:20, 4 May 2011 (UTC)

how to format my olcp XO 1

please please i can ask you how to format the olcp and how to remove the downloaded applicattion which can not be erased please if u know it tell me quickly or send it on my email : saemscolomb@yahoo.fr

One way to clear all changes would be to re-install or update to a current version. See Release_notes/11.3.0#XO-1 or Release_notes/11.3.1#XO-1 (almost released). --FGrose 17:27, 10 June 2012 (UTC)

Super trouble with OLPC

hello friends! (first pardon me with the bad English...)

well, actually I'm repairing an XO-1 laptop OLPC, at the beginning it worked flawlessly, until i upgraded the bios firmware downloaded from: http://wiki.laptop.org/go/OLPC_Firmware_q2e45, after the process, it won't boot anymore. the trouble is i can't figure out how to make it boot... i installed this build: http://wiki.laptop.org/go/Release_notes/11.2.0 no luck... always end in the OK command prompt... same thing happened to every build version I've tried, downloaded and installed from here: http://wiki.laptop.org/go/Release_notes also, I've tried to re flash the bios and no luck, i use several ROM files, from the Q2E41(the original ROM bios that comes in my OLPC) to the last Q2E45, and still no luck... I've tried to install SO images with several SD cards with 1, 2, and 4 GB of storage capability, all of them formatted in several ways: FAT, exFAT, vFAT, FAT12, FAT16, and FAT32... and nope...the OLPC won't boot... then I've tried luck with 2 kingston USB memory sticks, one is a 1GB and the other is a 8GB storage capability, tried with FAT, exFAT, vFAT, FAT12, FAT16, and FAT32 formats, it install the OS image in the OLPC, but still the laptop won't boot... Tired of this, i get a developer key from here: http://wiki.laptop.org/go/Activation_and_developer_keys, and tried it without any luck at all...

NOTE # 1: the OLPC hardware test report that everything is good...

NOTE # 2: all builds and bios I've downloaded and used to restoring my OLPC were for the XO-1 laptop model.

NOTE # 3: all clean-install and bios writing processes ended correctly with no failures.

NOTE # 4: the battery is fully charged, and the AC adapter is in outstanding performance.

NOTE # 5: all the internal memory chips are in good shape, also I've made this process: http://wiki.laptop.org/go/XO_Flash_Bad_Blocks, and the flash nand only got around 15 bad blocks... then i made this process: http://wiki.laptop.org/go/Fix_Clock and nothing, the OLPC always ends in the OK prompt, and never run the installed OS image...

anyone can light any clues about what is wrong with this OLPC???

any responses here or in my e-mail dj.electron@gmail.com with help to solve this mystery, are welcome .

Regards!!!

downloading stuff

I want to download stuff on my XO laptop, but it keeps taking me to archive manager, which I don't like. I need instructions now!!!

that is probably because you are downloading files that can only be opened by archive manager. exactly what files are you downloading? perhaps the files are not designed for your XO laptop. --Quozl 22:34, 11 October 2012 (UTC)

Technological and estructural diagram of the OLPC project

I am a volunteer at an organization that implements the OLPC project in Honduras. I am trying to help in different areas and one of them is to create documentation that will guide the end users of the program. This documentation is aided with descriptive images and one of them, which I need from you is the one that has the diagram of the structure of the OLPC project (technology oriented). I was looking at some links that show this diagram but I can not find it anymore. It has an oval of the acronym OLPC in the center and it branches out to the left with technology and to the right with outreach and education. It will be of great help if you can provide me with such an image.

Thank you,

Alvin, mesh

I have a couple of XO's with me. I would like to change the network protocols and analyze the results.

I would like to know where is the mesh protocol located on the XO? From where can I change the protocols?

Thanks in advance.

Hello. The mesh protocol is only available on the XO-1 model. Confirm you have an OLPC XO-1 model first. The OLPC XO-1.5, XO-1.75 and XO-4 models do not have mesh. Next, the mesh is implemented inside the wireless module firmware, with some small functions in the Linux kernel. Because it is in the firmware, you cannot practically change the protocol. --Quozl 03:44, 8 April 2013 (UTC)
Hello Again thanks for a quick response earlier. Yes I have XO-1. I have some more Questions. Is there any way I can change the protocols in XO-1. Will I be able to change the Network Protocol Parameters? If Yes than how? Thanks in advance.
It depends on which protocol you wish to change. No, the mesh physical protocol cannot be changed. Yes, all the other network protocols above the physical layer can be changed, using Linux commands, Linux kernel run-time configuration parameters, and Linux kernel build-time configuration parameters. Which specific protocol and parameter do you wish to change, and why? --Quozl 01:00, 9 April 2013 (UTC)
Thanks for the information earlier. My interest is in the routing. I am doing a research on the mesh protocols. Some more questions to answer please. (1) Is the routing (and the corresponding layer) is part of the firmware too? (2) Which application layer software (GUI..etc) do they include to enable students to create links and task on the mesh? Thanks in advance.
It is of historic use, I guess. XO-1 mesh implementation was not continued beyond XO-1. Our XO-1.5, XO-1.75, and XO-4 models use ad-hoc rather than mesh. To answer your questions: (1) Routing on the mesh is entirely handled by the wireless module firmware. It is an implementation of IEEE 802.11s draft. It is incompatible with IEEE 802.11s final. (2) Sequence is: user selects Sugar network view, then clicks on a Mesh icon. Sugar sends mesh request command to Network Manager daemon. Network manager sends command to kernel. Kernel sends command to wireless module via USB. Reply cascades back up the stack, and the Mesh icon is changed to show it is selected. User starts a Sugar activity and enables sharing. Activity uses multicast UDP to advise activity is available for sharing. Other nodes on the mesh receive the UDP and update their network view. --Quozl 03:39, 9 April 2013 (UTC).
Thanks for the information earlier. Will I be able to get a chance to edit wireless module firmware? thanks
Chance: 0.1% Because it is in the firmware, you cannot practically change the mesh protocol. The firmware is the property of Marvell. The source code is not public. The firmware is in the file usb8388.bin which is stored on the laptop. The file is sent to the wireless module after power is turned on. There is no public documentation for the ARM and baseband processor on the module, and these chips are from a silicon design around 2005, and probably no longer available. The module is soldered to the main board. --Quozl 04:58, 9 April 2013 (UTC)
Hello, I have some more questions. The network is usually organised in a few layers, traditionally in seven. The lowest layer is the physical layer. That is indeed firmware and cannot be edited. Above that we have the data link, network, and transport layer. Routing will happen in one of these layers, usually in the network, sometimes in the data link layer. Question is: where is the routing taking place for the OLPC XO-1 and the other versions of OLPC XO (like XO-1.5 ..etc). thanks.
We use TCP/IP for networking on OLPC XO, and TCP/IP is not based on a seven layer model. Wikipedia has an article that describes OSI and TCP/IP layering differences. Routing happens in as many layers as are required by the definition of those layers, not only one. There are two layers that contain routing for XO-1, and one for XO-1.5, XO-1.75, and XO-4. The mesh on XO-1 automatically maintains a list of mesh nodes in the wireless module, considered to be physical routing. The other layer is TCP/IP routing, which is provided by Linux, and is not unique to OLPC XO, so it would be redundant to describe it here. Look for a text that describes TCP/IP. --Quozl 01:32, 10 April 2013 (UTC)
Hello. I would like to know, is there anyway where the protocol parameters and be changed and analyzed? Thanks.
Your question is ambiguous. If you mean the mesh routing, then [1] may help you. If you mean Linux routing, then consult a text on TCP/IP and Linux. --Quozl 23:13, 10 April 2013 (UTC)
Hello, sorry. I would like to know if mesh routing protocol parameters on OLPC laptops can be altered (modified/changed) and analyzed? thanks
See Wireless_Driver_README, RELEASE_NOTES and Mesh_Forwarding_Table. Please also consider Mailing_lists ... the Devel mailing list is a more suitable place for this discussion, and you would find a larger audience. --Quozl 00:28, 11 April 2013 (UTC)

Who has heard this OLPC "nerdcore" rap song?

The nerdcore rappers called "Dual Core" published a song about the OLPC on Jun 17, 2013. Find it on YouTube here. With only 3,930 views recorded as I write this on June 21, 2017, it would appear that a great many more people might want to give it a listen. Maybe you? - Docdtv 08:28, 21 June 2017 (UTC)
